language support

https://typedrawers.com/discussion/222/tool-for-language-support-testing

i found from that article, this software can know it. can you help me how to do that? i can’t find in user manual

FontCreator has no such utility, but there are numerous transform scripts that will add additional characters to your font.

You can also use the Insert Glyphs or the Insert Characters feature to add multiple characters at once.

okay, do you know the right tools?


i know some tools, but someone tellme that’s some language are not really correct. so i just afraid to use it for misunderstanding
