In GNOME 3.10 we’ll have translated ICC profiles thanks to all the translators. This should make Alexandre Prokoudine happy indeed.
For applications, libcolord provides a CdIcc GObject if you don’t feel like dealing with wchar_t‘s and ‘mluc‘ objects yourself. Applications that deal with ICC profiles and want to get the localized versions of the description should probably look at this example code in C or in Python.
Comments, as always, welcome.
