Assertions when doing Export As... (#10321)

Browse Source 
Fix assertion with gcc 6: The comparison function must be a strict weak
orderings and not give x < x.

Fix assertion when a custom exportable document format is given a non-ASCII
name. Use qt_ to be consistent with the rest of the code.

Use Qt's locale-aware comparison for appropriate sorting.
