name & description of aem files are not decoded correctly

[Art-Ev]

aem matrices reader is missing ".decode('utf-8')" somewhere, this results in strange strings along qaequilbrae menus

• name : displayed with the "bytes letter", example b'matrix name' (present in : project data, "Traffic classes" in "traffic assignment", desire lines)
• description : not displayed at all in project data widget

Is this only the case for non-english QGIS installation ?

@pedrocamargo or @r-akemii : do you now at which level this need to be adressed to not broke things like assignment or desire line computation ?

[pedrocamargo]

That's a good question. I am pretty sure this would be an issue in the Python library, though, so I will ask @r-akemii to take a look at this.

@Art-Ev are these decoding issues persisting? I use a non-English QGIS installation here and the only time I've noticed these byte letters was when a matrix wasn't saved with a name, but otherwise, they have never appeared here. For instance, this is a screenshot of a Sioux Falls test set here. The decoding for AEM format seems to be working fine.
