           Summary: ACL bug - passwords with special ascii character
                    throwing exception and cant be used
          Severity: bug
    Classification: Unclassified
                OS: Windows
          Reporter: Bastian.Wassermann at multivac.de
          Hardware: PC
            Status: UNCONFIRMED
           Version: unspecified
         Component: Mercurial
           Product: Mercurial

I am from germany and our "central repository" is protected by ACL. This works
fine for most time, but if we try to use a password with special german Ascii
character (Umlaut), a error message will be thrown and we can not login.

It is easy to reproduce, by taking a password with Ascii 0x99 (Ö) and try to
pull from ACL protected repository. We have tried this on Windows XP and
although Windows 7.

Cmd commands:

hg pull
http authorization required
realm: our-server
user: my-username (fixed in .hg/hgrc)
password:
