BUG : skip looking up expanduser if unicode error #3532
Conversation
closes matplotlib#3516 by ignoring the real problem. The real problem seems to be in the core libary ( http://bugs.python.org/issue13207) to which the response was 'upgrade to python 3'.

@mmagnuski Can you test this to see if it fixes your problem? I don't have a windows machine handy... |
|
Perhaps, a warning should be added about it being ignored and suggest python3 if the user home path must be used and is not completely ascii |
|
On the other hand, that is a set of things that are unlikely to change quickly and we would just be spamming the users with a redundant warning every time they start up. On the other-other hand it would head off the 'mpl is not reading my rcparams' bug reports. |

@mmagnuski: I think you're now running into #3487, which is fixed on the maintenance branch but not in any release yet. |
|
There are a couple of alternative solutions suggested here: https://stackoverflow.com/questions/23888120/an-alternative-to-os-path-expanduser Great if that works. I'm wary of including a lot of very low-level and platform-specific code, though, particularly since Windows gets so little testing as it is... |

Closing in favor of #3594 which actually fixes the problem instead of ignoring it. |
