Now that I have intermediate files for everything, I can inspect the entire pipeline to see which program screwed things up: $ grep -an '\$' iconv.1.* iconv.1.col:115: $ iconv -f ISO-8859-15 -t UTF-8 < input.txt > output.txt iconv.1.col:120: $ echo abc à α ⬠à á¸Ã§ | iconv -f UTF-8 -t ASCII//TRANSLIT iconv.1.eqn:174:$ \fBiconv \-f ISO\-8859\-15 \-t UTF\-8 < input.txt > output.txt\fP iconv.1.eqn:183:$ \fBecho abc ß α € àḃç | iconv \-f UTF\-8 \-t ASCII//TRANSLIT\fP iconv.1.grep:115: $ iconv -f ISO-8859-15 -t UTF-8 < input.txt > output.txt iconv.1.grep:120: $ echo abc à α ⬠à á¸Ã§ | iconv -f UTF-8 -t ASCII//TRANSLIT iconv.1.grotty:1726:t$ iconv.1.grotty:1789:t$ iconv.1.troff:193:$ \fBiconv \-f ISO\-8859\-15 \-t UTF\-8 < input.txt > output.txt\fP iconv.1.troff:202:$ \fBecho abc � α � à�ç | iconv \-f UTF\-8 \-t ASCII//TRANSLIT\fP It seems that it's eqn(1) that does this.
