Hello,
I am trying to find the rules (or the logic) behing nodeprep
processing as done by many libraries.
Nodeprep adds forbidden characters to usual stringprep tables. Among
those characters we find "/" (47).
Some libraries extend it to caracters such as c/o (8453). The rational
behind that is that it contains a fraction.
Is there somewhere a complete list of such unicode characters that are
implicitely forbidden by the following section of the Nodeprep RFC:
"In addition, the following Unicode characters are also prohibited:
#x22 (")
#x26 (&)
#x27 (')
#x2F (/)
#x3A (:)
#x3C (<)
#x3E (>)
#x40 (@)
"
I end up wondering why this other types of fractions are often
accepted by nodeprep libraries:
1/4: 188
1/2: 189
3/4: 190
Fraction Slash: 8260
1/8: 8539
3/8: 8540
5/8: 8541
7/8: 8542
Division slash: 8725
Any pointers are appreciated.
Cheers :)
