I understand that this could be somewhat subjective so I’ll try to outline the parts that I’m mostly sure about to narrow the focus as much as possible.
I want to do some rudimentary login name checking. My goal would be to allow all unicode characters that would be used in a name including in non-English languages + numbers and basic punctuation that could be in a name but not writing punctuation like
!, ? nor control character like CR, LF and so on and white space is allowed in this case.
The obvious things to allow would be:
unicode.IsLetter and to not use
IsControl but I am unclear with
IsMark as it looks like a subcategory would be useful but another not and have no idea about
IsGraphic and unsure about
Has anyone delved into unicode enough to have an idea on what would be a reasonable selection of allowed unicode?
