- VCMI can now be compiled in C++20 mode
- Replaced all references to C++17 with C++20
- Boost 1.74 is now set as minimal version (older version might work but
untested)
- Updated documentation to reflect required versions of compilers /
libraries
- Removed excessive fail-fast / continue-on-error from CI
Now VCMI will use either preferred language or install language to load
maps and campaigns that are part of "core" mod, or, in other words -
placed in Maps directory of H3 data (like most of manually downloaded
maps and campaigns are)
If game data is in English, then game can safely use encoding of player-
selected language (such as Chinese) to load maps. After all, both GBK
and all Win-125X encoding are superset of ASCII, so English map will
always load up correctly.
Maps that are part of a mod still use mod language as before - it is up
to mod maker to correctly set up mod language.
