What is a glyph?
Glyphs are additional characters that can be used in fonts. These characters can allow you to use letter accent marks, access other characters in the language, and even add more decorative letters to use in your fonts.Look at the example below where we can access glyphs to add some decorative letters to the word's beginning and end.
Knowing that not all fonts have extra glyphs is important. It depends entirely on the font's creator. When creating the font, the glyphs need to be designed.
