That used to be true, but then xterm(1) has -fb support for a `bold' font to support same-glyph overstrike with `x^Hx', and then Unicode got in on the act with combining characters. $ printf '\0%s\040\336\0 ' a b c | iconv -f ucs-2be; echo a⃞ b⃞ c⃞ $ Don't think this helps with Bernd's issue though. :-) There is U+0331, combining macron below, `U̱ṉi̱x̱', and lots of other combiners. Don't know offhand of a `plus' for overlaying a `0' in -Tutf8. Bernd, I think you need to Google up `pinyin and unicode'. Cheers, Ralph.
