Online language tool for supported languages

Forums: 

Hi guys,

glad to join this great place.

I have a question: do you know any online tool (or any clever method) to display languages list which are supported by the font? I'm making one and it contains German, Polish & Spanish glyphs, but I don't know which other languages are using the same glyphs as mentioned.

How can I check it ?

Cheers and thank you in advance.
