 Taking trep out of the default features works nicely, but since in
 this case I want quote-replacement as the default and straight
 quotes only occasionally, I ended up with the following solution:
 
 \definefontfeature[default][liga=yes,kern=yes,tlig=yes,trep=yes,mode=node]

You can add a feature with this:

\definefontfeature[default][default][mode=node]

 \definefontfeature[notrep][liga=yes,kern=yes,tlig=yes,trep=no,mode=node]
 \def\realquotesingle{{\setfontfeature{notrep}'}}


Another option is to disable only a single feature:

\definefontfeature[notrep][trep=no]
\def\realquotesingle{{\addfs{notrep}'}}

Thanks, that's more elegant. I've updated the wiki page to include it.

Just a question for Hans or Taco: would it be possible to create a
command sequence that would avoid doing the auto-replacement even when
trep is on? Say, \textapostrophe, \asciiapostrophe, \textquote,
\asciiquote or some similar name.

One option would be to automatically create a virtual font with
duplicate of 0x27 at some constant slot and then access that glyph
(even though that might have consequences for searching in PDFs). This
is ugly, but maybe there is some better and more elegant approach.

 ' : \lettersinglequote, \quotesingle

This is the right one, but if autoreplacement 0x27-0x2019 is on, it
doesn't help - this will still generate the curly 0x2019.

 Hello,

 This may be a stupid question, but I can't work out how to produce the
 ' character (quotesingle, unicode 0x0027) glyph in a document. Just
 typing the character in the source produces a quoteright as expected.
 Here are my other attempts:

 \starttext
 \quotesingle
 \getnamedglyphdirect{lm}{quotesingle}
 \uchar{00}{39}
 \stoptext

 They all produce quoteright as well. Does anyone have a better
 suggestion? I'm using MkIV, version 2011.02.25 22:03.

In font-ini.mkiv you can find

\definefontfeature
  [default]
  [%mode=node,
   liga=yes,kern=yes,tlig=yes,trep=yes] % texligatures=yes,texquotes=yes

You can find those features defined in font-otc.lua, but in short:
trep is responsible for auto-replacing 0x0027 into 0x2019. If you want
to disable that behaviour, you need to turn trep feature off, for
example with
\definefontfeature[default][liga=yes,kern=yes,tlig=yes] % trep=no
to be more explicit

Sometimes you need to load the font after redefining the features, but
I'm not sure when that is and maybe I'm wrong (it might be true for
Type1 fonts or I may be wrong completely).

Mojca

PS: just as a thought ... it might make sense to map 0x27 to some
(constant) private range slot and make it accessible with some control
sequence. I don't know to what extent that would be usable though, so
maybe that's just a way too silly idea.

You need node mode for that stuff to work.

Taking trep out of the default features works nicely, but since in

quotes only occasionally, I ended up with the following solution:

\definefontfeature[default][liga=yes,kern=yes,tlig=yes,trep=yes,mode=node]
\definefontfeature[notrep][liga=yes,kern=yes,tlig=yes,trep=no,mode=node]
\def\realquotesingle{{\setfontfeature{notrep}'}}

\starttext

Straight quote: \realquotesingle

Standard quote: '

\stoptext

Will wikify later today in case anyone else ever needs this.

Done: http://wiki.contextgarden.net/Quotesingle . At present it is
