Problems using wingdings true type font on APP

Hi’

I’ve a problem with my first APP that uses a wingdings font to show many symbols on text messages and button.

When I test the app on SDK platform with WIN10 I see a correct text, but when I deploy the apk on android 5.0 the wingdings font was replaced by native system font. 

This problem occours only with wingdings tt font; I’ve tried other fonts and it works fine.

I read the blog and the forum to search a solutions and I’ve tried these solutions:

· Putted the ttf file in the same folder of mail.lua

· Renamed the file with lowercase

· Renamed the file ttf like family name: “wingdings2.ttf” for file and font family

but the error persists.

Anyone have an idea to solve my problem?

Many thanks,

Paolo
