Another MapleStory .wz file parser written in C++ 17

wzlibcpp

modern first, more easier, cleaner api and support cross-platform

Status

⬜️ utf8 formatted string with std::string

⬜️ remove all of older (deprecated) api - [[deprecated]] attribute is currently marked.

☑️ modern api

☑️ cross-platform

Dependencies

• zlib
• mio - for mmap (aka file mapping in windows)
