wxGUI: encoding error when saving workspace

[mlennert]

Trying to save my workspace, I get the following error:

Échec d'écriture des paramètres de l'espace de travail courant.

Raison: 'ascii' codec can't encode character u'\u20ac' in position 34: ordinal not in range(128)

Traceback (most recent call last):

UnicodeEncodeError: 'ascii' codec can't encode character u'\u20ac' in position 34: ordinal not in range(128)

The weird part is that I don't even know where I would have a non-ascii character. Maybe some translation has happened of parameters for the workspace parameter file ?

Vaclav made me realize that I did have a non-ascii character in my display: u'\u20ac' is a Euro sign.

Replying to mlennert:

This does not make this less an error, though. I suppose this is linked to the GSoC cartography work trying to save more elements of the current map display ?

In 70531:

wxGUI: encode values when saving workspace with overlays (see #3275)

[marisn]

There have been fixes for #3340 related to encoding. At the moment loading/saving workspace with various non-latin chars seems to work fine. Can this be closed?

r70531 still needs backporting so I would keep this ticket open until that has happened. Changing milestone to 7.2.2 to harmonize with the rest.

Backported in r71057.
