The Windows command prompt uses fixed width fonts.
This is fine for most western languages as well as Chinese, Japanese, and Korean.
But for some languages fixed width fonts are not really possible in the same way. Windows is still distributed in countries with such languages.
In Thailand, using a standard local version of Windows 10, if you open a command prompt and type "dir" in a directory with files using Thai script int the filenames, do you see the Thai filenames, or do you see boxes as in a typical Western Windows 10?
If you see Thai script, which Thai font is used?
