Hi,
There are two issues here:
1. You are also using a dash-like character, \o4255. The Emacs
[:alnum:] class
does not match this, therefore this character will continue not
to be
recognized. Use the underscore in property names, I am supporting
this.
Mmm... I used the normal underscore, _ (95, #o137, #x5f, U+005F). I
don't find \o4255.
2. Think twice before using non-ascii characters in property names.
This will make you file non-portable. If you send it to someone
living in a different locale, he/she might find the file broken.
ASCII doesn't work with my language (ex: Spanish); therefore I
don't use it.
But what I used is Unicode, and I wouldn't call it „non-portable"
nowadays (it works everywhere on the Internet and operating systems).
Even if „there can be programs which don't support Unicode", that's
not a reason to not using Unicode; what we must do --in my opinion--
is fix the programs.
