Can't see (and thus can't open) accented files with LC_ALL=C

[naoliv]

I have some files with accents in their names (for example, Capitólio.gpx)
While running JOSM with pt_BR.UTF-8 I can properly see them at the Open dialog (File → Open).

With LC_ALL=C, however, JOSM doesn't display any of these files.

To test, create some test file, like á.osm, export LC_ALL=C, open JOSM and try to locate this file.

In LC_ALL=C, the charset is ASCII, so what do you expect?

[naoliv]

The problem is that JOSM doesn't display anything, not even with the wrong codification.
For example, in a directory with the files á.html á.odt á.osm á.png and LC_ALL=C exported.

With libreoffice:

Chromium/Chrome:

While it doesn't display any name, I can click at the file and open it:

geeqie:

Firefox:

But with JOSM:

[bastiK]

As you demonstrated with Chrome, GUI apps don't work properly when LC_ALL=C is set and filenames contain non-ASCII characters. Why do you think JOSM should work with LC_ALL=C, what is the reason to run it like that?

[naoliv]

I use LC_ALL=C to report some tickets here and to see the original phrases (in buttons, dialogs, etc). Basically to say the necessary steps to reproduce a problem.

[stoecker]

Why not use "--language=en" as commandline argument?

[naoliv]

Because I didn't know about this :-)
I guess this ticket can be closed then.
Thank you!

An alternative would be to use LC_ALL=en_US.UTF-8.
