hplib (hp-sendfax) on Fedora 11 causes Stacktrace on UTF-8

Asked by M.Ende on 2009-09-22

If I try to send a fax (from openoffice) using the cups-printer and hp-sendfax I'll get this Stacktrace from hp-sendfax (same error occures when I'm using hp-toolbox). Printing and scanning is not affected.

I'm running Fedora 11 (LANG=de_DE.UTF-8 , x86_64)

It's this line which causes the mentioned Error:

self.title = unicode(utils.xrstrip(title, '\x00'))[:64].encode('utf-8')

This occures when the title of the document contains non-ascii-characters (like üäöß..)
If you keep ascii-only everything works.

I'll file that as an issue

Well, M.Ende. It does not help. At all. And how to UTF8ized this script? By the way I use Cyrillic.

Ivan,

I've tried several times around with the utf-8 conversation. After fixing the UTF-8 I had issues with the date,
which is processed near by this line. After spending much time in the UTF-8 problems I had decided not
to follow this issue anymore. Now I'm using ASCII-Only filenames. This way I'm around this issue.

After working on this, I had realized that UTF-8/Unicode/Ascii-transcodings and python aren't really good friends. :(
