Ive always thought that Serbian is the worst off out of all European languages. Both cyrillic and latin script is widely used. Latin also has a naked variant, where all diacritics are left out (which is especially prevalent online). Also, it is non-EU, so initiatives like [0] will only indirectly help with representation (croatian being the same language, but it does not use cyrillic script)
