UnicodeEncodeError with non-ASCII character in environment

[roehling]

On my system, I have the environment variable DEBFULLNAME=Timo Röhling (note the non-ASCII umlaut in my last name) set, which causes catkin build to raise the following exception:

[build] Found '275' packages in 0.0 seconds.                                   
[build] Package table is up to date.                                           
[build] An internal error occurred!

    raise self._exception
UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position 484: ordinal not in range(128)

Once I unset DEBFULLNAME, everything works.

You can reproduce the bug by running eval $(printf 'export NON_ASCII=\xc3\xb6') at the bash prompt before invoking catkin build.

Thanks, @roehling. This is definitely with 0.4.0, but can you tell me not about your OS and Python version?

[roehling]

It's Ubuntu 14.04 LTS ("Trusty") with Python 2.7

@roehling thanks!

I came up with a more useful stack trace by running catkin build --get-env:

@roehling Thanks for the additional stack trace, #342 should fix your problem. I hope catkin_tools didn't offend you!

[roehling]

@jbohren thanks for the quick fix!
