Selectors don't support low Unicode characters (eñe)

Unicode support in selectors is flawed and does not allow usage of certain unicode characters (Spanish accented letters, or eñe for example).

Patch provided.

Not sure if the new range (starting from \\u00c0) is the most appropiate.

Does this support eñe as well ?

Question is, are they really valid characters to be used on id's, class, etc ?

I googled that (very quickly) and couldn't find the answer.

Ariel:

There are differences between HTML and XHTML (or XML) for this case.

Class attributes are CDATA in both cases. Any character is allowed. See http://www.w3.org/TR/REC-html40/types.html#type-cdata

Id attributes are defined as type ID in HTML and the character set is restricted. See http://www.w3.org/TR/REC-html40/types.html#type-id

But in XML (XHTML) are defined as names, and most of the restrictions don't apply: http://www.w3.org/TR/REC-xml/#NT-Name

About the patch, yes, it will accept "eñes". This is the proposed change:

- "(?:[\\\\w\\u0128-\\uFFFF*_-]|\\\\\\\\.)", 
+ "(?:[\\\\w\\u00c0-\\uFFFF*_-]|\\\\\\\\.)",

resolution:	→ fixed
status:	assigned → closed

That's an easy fix, just landed it in Sizzle, will push to jQuery soon.
