I would like to use some not-so-common diacritics and maybe some fancy Unicode characters in my Android app, but I could not find a charmap for Roboto.
What glyphs or character sets are included in Roboto Regular, Bold and Condensed fonts?
After a bit more searching, I've found this reference on the Google API's site
http://commondatastorage.googleapis.com/androiddevelopers/design/Roboto_Specimen_Book_20131031.pdf
The updated reference for the latest version of the font files is here
https://github.com/google/roboto/blob/master/res/glyphlist.txt
Note that this may be more recent than the version on your Android IDE or OS!
