Code

    for obj in env.objects:
        if obj.type == 'Font':
           font.m_FontData = open(font_file_path, 'rb').read()
           font.save()
    with open(another_file_path, 'wb') as f:
        f.write(env.file.save())

A lot of game use glyphs instead of normal fonts,
in such cases, it's not possible to edit the font data that way.

Exporting, to say nothing about editing, glyph based fonts isn't supported atm yet either,
because it's very difficult to convert them into a normal font, due to the way fonts work.
