Yep, it works even if they are used within a single line of text. I first tried to use the GNU iconv() but that function was just incredibly stupid so I wrote my own. While writing it I realized I can just autodetect all input on char-by-char basis, skip most of the “offical” conversion tables and just focus on US-ASCII/Latin-1/first plane of UTF-8. My strniconv() is purely a 80/20 implementation, and that’s good enough for me.
