Created attachment 5204 sample file ISO-8859-* encoded files are not recognized automatically. Mousepad suggests "System (ANSI_x3.4-1968)" encoding which can't handle these files properly. Just for comparison: gEdit cannot guess the file encoding, it defaults to UTF-8. Geany, mEdit, Notepad++ and Scite open the file correctly. Vim, nano and jEdit open the file but incorrectly render the non US-ASCII as '?'.
Maybe libicu(as an optional dep) could help: http://userguide.icu-project.org/conversion/detection
