We suggest that before you purchase a commercial version in order to use the additional glyphs, you should check if the program you use support these feature. Actually, the easiest is to use Adobe Illustrator or InDesign. Just click on Text > Glyphs and you’ll get the complete character map of the font. Adobe Photoshop, in it’s latest version (CC 2015) offers such a feature : click on Type > Panels > Glyphs panel or Window > Glyphs. For any other program, please verify if you can access the character map. Hopefully, for any font with additional glyphs, We’ll add a separated font file with only the alternates with a character map, so that you could easily use them, even in Microsoft Word.
