- Users MUST NOT log feature requests, ideas, or suggestions unrelated to Monero code or Monero's dependency code or Monero's potential/future dependency code or research which successfully implements Monero.
- Users MUST NOT log any solutions to problems (verifiable or hypothetical) of which are not explicitly documented and/or not provable and/or cannot be reasonably proven.
- Thus, the release history of the project MUST be a list of meaningful issues logged and solved.
- To work on an issue, a Contributor MUST fork the project repository and then work on their forked repository.
- To submit a patch, a Contributor MUST create a Platform pull request back to the project.

+- All Public Contracts (APIs or protocols) SHALL be documented.
 - All Public Contracts SHOULD have space for extensibility and experimentation.
 - A patch that modifies a stable Public Contract SHOULD not break existing applications unless there is overriding consensus on the value of doing this.
 - A patch that introduces new features to a Public Contract SHOULD do so using new names.
 - Old names SHOULD be deprecated in a systematic fashion by marking new names as "experimental" until they are stable, then marking the old names as "deprecated".
 - When sufficient time has passed, old deprecated names SHOULD be marked "legacy" and eventually removed.
- Old names MUST NOT be reused by new features.
+- Old names SHALL NOT be reused by new features.
 - When old names are removed, their implementations MUST provoke an exception (assertion) if used by applications.

 ### Project administration

+- A new Contributor who makes a correct patch SHALL be invited to become a Maintainer.
 - Administrators MAY remove Maintainers who are inactive for an extended period of time, or who repeatedly fail to apply this process accurately.
 - Administrators SHOULD block or ban "bad actors" who cause stress and pain to others in the project. This should be done after public discussion, with a chance for all parties to speak. A bad actor is someone who repeatedly ignores the rules and culture of the project, who is needlessly argumentative or hostile, or who is offensive, and who is unable to self-correct their behavior when asked to do so by others.

 ## Introduction

 Wownero is a privacy-centric memecoin that was fairly launched on April 1, 2018 with no pre-mine, stealth-mine or ICO. Wownero has a maximum supply of around 184 million WOW with a slow and steady emission over 50 years. It is a fork of Monero, but with its own genesis block, so there is no degradation of privacy due to ring signatures using different participants for the same tx outputs on opposing forks.

-## Supporting the project
-
-Wownero is a 100% community-sponsored endeavor. Supporting services are also graciously provided by sponsors:

-### Open Collective
-
-Open Collective is an online funding platform for open source software and collaborative communities. The platform brings together legal entities that act as a “Fiscal Host”, “Collectives” (unincorporated, community-based projects), and individuals interested in supporting projects with donations. Fiscal hosts hold donations for collectives in trust and handle all the taxes and legal stuff.
-
-Wownero is hosted by Open Collective Europe, a Brussels-based non-profit that hosts many other collectives, such as Manjaro, EndeavourOS, Xfce, and peertube.social. If you would like donate to the Wownero Project using this method, you can check out our [Wownero - Open Collective](https://opencollective.com/wownero) page.

-## Release staging and Contributing
-
-**Anyone is welcome to contribute to Wownero's codebase!** 
-
-If you have a fix or code change, feel free to submit it as a pull request. Ahead of a scheduled software upgrade, a development branch will be created with the new release version tag. Pull requests that address bugs should be made to Master. Pull requests that require review and testing (generally, optimizations and new features) should be made to the development branch. All pull requests will be considered safe until the US dollar valuation of 1 Wownero equals $1000. After this valuation has been reached, more research will be needed to introduce experimental cryptography and/or code into the codebase.
-
-Things to Do, Work in Progress, and Help Wanted tasks are tracked in the [Meta](https://git.wownero.com/wownero/meta/issues) repo. 
-
-Join `#wownero-dev` on IRC OFTC to participate in development conversation.

 ## Scheduled software upgrades

 Wownero uses a fixed-schedule software upgrade (hard fork) mechanism to implement new features. This means that users of Wownero (end users and service providers) should run current versions and upgrade their software on a regular schedule. The required software for these upgrades will be available prior to the scheduled date. Please check the repository prior to this date for the proper Wownero software version. Below is the historical schedule and the projected schedule for the next upgrade.
 Dates are provided in the format YYYY-MM-DD.

+## Release staging and Contributing
+
+**Anyone is welcome to contribute to Wownero's codebase!** 
+
+If you have a fix or code change, feel free to submit it as a pull request. Ahead of a scheduled software upgrade, a development branch will be created with the new release version tag. Pull requests that address bugs should be made to Master. Pull requests that require review and testing (generally, optimizations and new features) should be made to the development branch. All pull requests will be considered safe until the US dollar valuation of 1 Wownero equals $1000. After this valuation has been reached, more research will be needed to introduce experimental cryptography and/or code into the codebase.

-#
-# ``Backtrace_HEADER``
-#   The header file needed for backtrace(3). Cached.
-#   Could be forcibly set by user.
-# ``Backtrace_INCLUDE_DIRS``
-#   The include directories needed to use backtrace(3) header.
-# ``Backtrace_LIBRARIES``
-#   The libraries (linker flags) needed to use backtrace(3), if any.
-# ``Backtrace_FOUND``
-#   Is set if and only if backtrace(3) support detected.
-#
-# The following cache variables are also available to set or use:
-#
-# ``Backtrace_LIBRARY``
-#   The external library providing backtrace, if any.
-# ``Backtrace_INCLUDE_DIR``
-#   The directory holding the backtrace(3) header.
-#
-# Typical usage is to generate of header file using configure_file() with the
-# contents like the following::
-#
-#  #cmakedefine01 Backtrace_FOUND
-#  #if Backtrace_FOUND
-#  # include <${Backtrace_HEADER}>

-Subject: [PATCH] Fix build on arm64 architectures with some strict compilers
-
-This patch fixes an issue that occurs on 64-bit architetures under
-strict compiler rules. The code initially checked that the received
-size stored in 'uint64_t' was not bigger than the max value of a
-'size_t' variable, which is legitimate on 32-bit architectures where
-'size_t' variables are stored on 32 bits. On 64-bit architectures,
-this test no longer makes sense since 'uint64_t' and 'size_t' types
-have the same size. The issue is fixed by ignoring this portion
-of code when built for arm64.

-
-      Advantages over `std::stringstream` or `rapidjson::StringBuffer`:
-        - The internal buffer can be taken without a copy.
-        - The internal buffer can be given to `byte_slice` with zero
-          allocations for reference count.
-        - The internal buffer can be given to `zmq_msg_data_init` without a
-          copy or extra allocation.
-      an additional advantage over `std::stringstream`:
-        - Construction is significantly faster - the global `std::locale`
-          does not have to be acquired (global thread synchronization), and
-          an extra allocation for `std::stringbuf` is not needed (which is an

+// as far as support by the standard components used is concerned:
+
+// The various file stream classes, e.g. std::ifstream and std::ofstream, are
+// part of the GNU C++ Library / libstdc++. On the most basic level they use the
+// fopen() call as defined / made accessible to programs compiled within MSYS2
+// by the stdio.h header file maintained by the MinGW project.
+
+// The critical point: The implementation of fopen() is part of MSVCRT, the
+// Microsoft Visual C/C++ Runtime Library, and this method does NOT offer any
+// Unicode support.
+
+// Monero code that would want to continue to use the normal file stream classes
+// but WITH Unicode support could therefore not solve this problem on its own,
+// but 2 different projects from 2 different maintaining groups would need changes
+// in this particular direction - something probably difficult to achieve and
+// with a long time to wait until all new versions / releases arrive.
+
+// Implemented solution approach: Circumvent the problem by stopping to use std
+// file stream classes on Windows and directly use Unicode-capable WIN32 API
+// calls. Most of the code doing so is concentrated in this header file here.
