I need to have a dash (or a bar) over a letter in a name, say G\=o ro
for Goro, with one o "accented". The TeXBook tells me to do this: \=o
for the dash over o. It does not seem to be working. I also tried \={o}
which is on AMS website (since I am using AMSTeX), but it is not working either. I am puzzled, because other accents over letter seem to work.
Please note, the claim that the question has been answered before is incorrect, since the answers referred to concern Latex, not AMSTeX. See further discussion down below. Therefore, the problem has not been solved yet.
Minimal example
\input amstex
\documentstyle{amsppt}
\document
\={o}
\enddocument
\={o}
works find for me... but I suggest using unicode input encoding and writingō
directlytabbing
-like environment which redefines\=
(in which case you need to use\a={o}
, if I recall correctly)?
