Description Łukasz Posadowski 2013-05-31 07:45:59 UTC 
Description of problem:
When I create user in anaconda I can enter my real name and username. My real name is Łukasz and username entry is filled automatically. And then anaconda crashes. I can type Lukasz as real name and everything is fine.

Version-Release number of selected component (if applicable):


How reproducible:
I tried it once.

Steps to Reproduce:
1. Create user in Anaconda (while installing packages)
2. type non-latin character in real name.

Actual results:
installer crashes

Expected results:
Be Łukasz.

Additional info:
I know that username generally shouldn't contain "Ł" character, but anaconda use it anyway. It crashes in the process, but even if it wouldn't, it's still bad idea to have "łukasz" username.
Comment 1 Łukasz Posadowski 2013-05-31 08:13:27 UTC 
More additional info:

When I type "Łukasz Po" anaconda says:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc5 in position 0: unexpected end of data - anaconda.
Comment 2 David Shea 2013-07-19 21:06:10 UTC 
Pushed a fix for the crash. As for translating the "Ł" in your name to "l" for the username, you're still going to have to do that manually. Anaconda uses the Unicode character definitions to remove diacritical marks. For example, "Á" is defined as equivalent to "A" plus an acute accent, so we remove the accent and use "a" in the username. For whatever reason, Unicode defines "Ł" as its own thing rather than being based on L, so we don't have a way to make that translation.

I attempted to reproduce this, but my report was detected as a duplicate of:
Bug 981608 - UnicodeDecodeError: 'utf8' codec can't decode byte 0xd0 in position 0: unexpected end of data

The user name was "lLłŁ" (from the attached log).
