Hi,
On Windows, we have the consola font. Consider the MWE:
\starttext
\definedfont[name:consola*default at 12 pt]
-
\stoptext
The output PDF is correctly generated with recent versions of ConTeXt LMTX.
The hyphen is, however, mapped to a soft hyphen
<https://unicode-table.com/en/00AD/> by means of the ToUnicode table which
contains:
beginbfchar
<015E> <00AD>
endbfchar
Consequently, when copying the text from the PDF and pasting in an editor
or a console, the soft hyphen is pasted.
I would like to change the ToUnicode information to an ordinary hyphen-minus
<https://unicode-table.com/en/002D/>:
beginbfchar
<015E> <002D>
endbfchar
I have tried with a goodies file, and an updated MWE:
--- 8< ------------------------------------------
return {
name = "consola",
version = "1.00",
comment = "",
author = "",
copyright = "",
remapping = {
tounicode = true,
unicodes = {
hyphen = 0x002D,
},
},
}
--- 8< ------------------------------------------
\definefontfeature[consola][mode=base, goodies=consola, unicoding=yes]
\starttypescript[mono][consolas]
\definefontsynonym[ConsolasRegular][file:consola][features=consola]
\stoptypescript
\starttypescript[mono][consolas]
\definefontsynonym[Mono][ConsolasRegular]
\stoptypescript
\definetypeface[Body][tt][mono][consolas][default]
\setupbodyfont[Body, ss, 10pt]
\starttext
\tt -
\stoptext
--- 8< ------------------------------------------
Unfortunately, this has no effect.
Please tell me how to correctly update ToUnicode information with a goodies
file.
Cheers,
Christoph

It is (as awlways with fonts) more complex than that (1) because
different unicode slots share the same shape and (2) we have some
(already) old hyphen patching code for messy fonts (which is kind of bad
anyway).
We actually want all these hyphens to have the right tounicode even if
they share shapes (i already had some comment about looking into that
but never ran into a font that needed it).
So, after some experimenting i decided to solve that in a different way
(lmtx only because there i have more control) ... i need to run some
checks and then do an upload so that you can test (also other files if
possible).

Finally I found the time to do some extended testing on this and it seems
that for my use-case the LMTX version 2021-06-09 behaves as I would expect:
Hyphens are now extracted as hyphens.
Thanks a lot for your implementation, Hans!
Cheers,
Christoph
