What do these Unicode characters (codepoints) mean in this regex?

Question

I have the following regular expression : I figured out most of the part which is as follows :

ValidationExpression="^[\u0020\u0027\u002C\u002D\u0030-\u0039\u0041-\u005A\u005F\u0061-\u007A\u00C0-\u00FF°./]{1,256}$"

u0020 : SPACE
u0027 : APOSTROPHE
u002C : COMMA
u002D : HYPHEN / MINUS
u0030-\u0039\ : 0-9
u0041-\u005A : A - Z
u005F : UNDERSCORE
u0061-\u007A\ : a - z

u00C0-\u00FF°./ : ??

Need help in understanding the final part of the validation expression :

u00C0-\u00FF°./

Anyone has any idea what does this mean?

Answer 1

\u00C0 - \u00FF are letters with accents on them, though that isn't all of them. And "°" is just the degree character. However, "./" should probably be "\." to permit period characters.

Answer 2

weird... according to the character map on Windows I'd say "À to ÿ"

Those are some variations (accents, cedillas) on A, C, E, I, D, N, O, U, Y, the german Sharp s, ...

Answer 3

Your question is mistitled, you want help with Unicode codepoints. You can check them, for instance, here.

They are the second half of Latin1 Supplement, including accentuated vocals and some other characters. See the above links.

Answer 4

It looks to be the range of characters presented in the last 2 columns in TABLE ASCII-II at the following link to The Extended ASCII Chart
