-------------
* On Windows, CMake learned to support international characters.
This allows use of characters from multiple (spoken) languages
in CMake code, paths to source files, configured files such as
``.h.in`` files, and other files read and written by CMake.
Because CMake interoperates with many other tools, there may
still be some limitations when using certain international
characters.
Files written in the :manual:`cmake-language(7)`, such as
``CMakeLists.txt`` or ``*.cmake`` files, are expected to be
encoded as UTF-8. If files are already ASCII, they will be
compatible. If files were in a different encoding, including
Latin 1, they will need to be converted.
The Visual Studio generators now write solution and project
files in UTF-8 instead of Windows-1252. Windows-1252 supported
Latin 1 languages such as those found in North and South America
and Western Europe. With UTF-8, additional languages are now
supported.
