Best thing I've come up with is to go over the unicode list and
identify which languages you want to support. You then use unichr to
construct a regex such as: '[%s-%s]' % (unichr(start of unicode
block), unichr(end of unicode block)).

[Typo: misplaced .encode("utf-8") in mail.]

I managed to get it work:
   (u'^(?P[-0-9A-Za-z]+)/(?P[-_.0-9A-Za-zıİğĞüÜşŞöÖçÇ ]
+)/$', 'search_in_all_packages'),

The key point seems to be using (u'^ ... instead of (r'^...

Maybe I had a problem with caching and the fact that I didn't use u'^
for the other rules.

I wish I could specify all the unicode letters (for all other
languages apart from Turkish) as something like \w.

What about other unicode characters? Such as special characters in
other languages? I'm developing a search engine which searches for
files inside Linux packages. Whenever somebody enters a Turkish
character as a search term, urls.py can't handle that. Somebody [1]
has found a workaround by accepting everything except for "/" in the
url. But I'm wondering if it could be dangerous for me as I'm doing a
database search.

My url patterns used to be like:

(r'^(?P[-0-9A-Za-z]+)/(?P[-_.0-9A-Za-z]+)/$',
'search_in_all_packages'),

Then I tried appending special characters, and some encoding stuff:
(r'^(?P[-0-9A-Za-z]+)/(?P[-_.0-9A-Za-zıİğĞüÜşŞöÖçÇ ]
+)/$', 'search_in_all_packages')
then
(u'^(?P[-0-9A-Za-z]+)/(?P[-_.0-9A-Za-zıİğĞüÜşŞöÖçÇ ]
+)/$', 'search_in_all_packages').encode("utf-8")

but none of them worked.

URL Patterns for URL Encoding Symbols

[Andy Dietler]

Right now I've got a URL pattern that works for letters and numbers,
but when a character like %20 gets thrown in it fails.

The pattern is this:

(r'^(?P\w+)/$', 'detail'),

Which works when I have:

domain.com/Friends/
domain.com/24/

but not for

domain.com/The%20Office/

How do I get it to accept the %20?

Thank in advance.
