No \aring?

No \aring?

Hello,

I'm having problems producing the \aring and \Aring glyphs.

I'm using \enableregime[windows].

Neither {\aring} nor the 8-bit character 229 'å' produce the desired 
result. They just print an 'a' without the ring.

This is pdfeTeX, Version 3.14159-13h-pretest-20010126-2.1 (Web2C 7.3.3.1)
ConTeXt  ver: 2001.4.9  fmt: 2001.4.16  int: english  mes: english

I have looked in the source and found a file named 'regi-win.tex'. I 
understand that this is an input mapping of characters. Right? I found one 
typo in the file, but no solution to my problem.

I created a test file that prints the named glyphs I found in that file 
(What would I do without 'vi' and regular expressions?). All looks OK 
except \ccedilla (typo: \cdedille), \ntilde, \Ntilde, \aring and \Aring.

The testfile can be found at: 
   http://www.xs4all.nl/~jgsusan/ConTeXt/test-regi-win.tex (5 Kb)

The PDF output can be found at:
   http://www.xs4all.nl/~jgsusan/ConTeXt/test-regi-win.pdf (41 Kb)

Could it be that not the input mapping, but the output mapping is wrong 
here?

Hans, any suggestion for a quick patch? I'm lost... I need \aring.

Thanks,

Joop

PS. An older version of ConTeXt had no problem with the 8-bit a-ring
    character. That was pdfeTeX, Version 3.14159-14f-released-20000525-2.1
    and ConTeXt ver: 2000.9.21

this is because the fall back of \aring is defined as 's', you can patch
enco-def: 

somewhere at the top:

\definecharacter textring          23

lower: 

\definecharacter Aring {\buildtextaccent\textring A}
\definecharacter aring {\buildtextaccent\textring a}
\definecharacter Uring {\buildtextaccent\textring U}
\definecharacter uring {\buildtextaccent\textring u}

pretty old pdftex

this is indeed *input* mapping [or sometimes intermediate mapping]

Ok, so we need to add:  

\definecharacter Ntilde {\buildtextaccent\texttilde N}
\definecharacter ntilde {\buildtextaccent\texttilde n}

indeed, there is no good fall back defined, thanks for pointing it out

patch enco-def.tex and regenerate the formats

this version of context has named glyph definitions instead of the less
readable accent/commans ones; the internals are still the same, except from
some enoding-to-encoding expansion improvements, but i redid the defs and
for sure missed a couple of glyphs, btw, these issues are unrelated to
pdftex [except that unicode searching for eastern european languagesis now
smoother].

recently pdftex didn't change that much [apart from protruding and hz
support], but version 14 is better than 13 in producing solid pdf code

Thanks Hans. Your patch instructions fixed my problem.

Now:
This is pdfeTeX, Version 3.14159-14h-released-20010417-2.1 (Web2C 7.3.3.1)
ConTeXt  ver: 2001.4.9  fmt: 2001.4.23  int: english  mes: english

Are ConTeXt Betas always against the latest pdftex snapshots?
 
Thanks,
