I'll list you the Unicode letters based on their order. Like for example, the null character would show first as it is U+0000. For the Unicode letters you can't see, I'd probably just give a description. It would be in this format. I am using A for example.

Unicode: U+0041

Glyph: A

Description: Just your standard capital A. It is used in the Latin writing system. Almost as much as used as E in english.
