Wow, super glad to know this is a recently discussed topic!
Yeah, I tried the tool to add special chars (á, é, í, ó, ú, ñ, →, ♥, etc...) to an already existing font I am using in a game project (importing the ttf). After exporting, all the font was (non-intentionally) scaled down.
I am not really familiarized with "DPI" terms and stuff. But it would be ideal to have a Scale% (100% by default, or the DPI stuff) variable at the export window so users could decide.
Thanks a lot for the tool you are providing to the community and for listening to us!!!!
