Unicoder
A Portable Wide-Character Terminal Output Package for C and C++
...Also, Unicoder can insert compiler specific commands that perform useful task such as clearing the console display or turn on bold and underline or change text font and background colors. And it provides a rudimentary way to draw on the display.
Currently, Unicoder supports Ubuntu-Linux GCC and on Windows it can be used with these IDEs and compilers: MS Visual Studio 2017&2019, Code::Blocks, Pelles C, Embarcadero Dev-C++, Open Watcom, MSYS, MSYS2, Cygwin and with MinGW, Clang, LCC and Digital Mars C (but Digital Mars does not support Unicode!)
