The iconv's "TRANSLIT" is not the transliteration that's sought here.
It's an attempt to present similarly-looking characters when the
original character is not in the target character set (ASCII in the
above snippet).  So it's a small wonder this only works for European
scripts, because no ASCII character can ever "look like" characters in
other scripts.
