Hello,

can someone help him? I have not much time at the moment.
Please CC him since he may not yet be on the list.

Hello Tobias,

A few days ago I have installed ConTeXt and since then I am
consistently trying to achieve the

  \usepackage{ae} % calls \usepackage[T1]{fontenc}
  \usepackage[latin5]{inputenc}

effect known from LaTeX.

Since it is doable in LaTeX, I am positive that it is also doable in
ConTeXt, I just do not know how yet.

I have composed two TeX files for ConTeXt to address the input
encoding issue.  (Those files are regi-il5.tex and enco-il5.tex.)
With regi-il5.tex I am able to type accented characters without any
problems, if you disregard hyphenation.  When hyphenation is taken
into account, I am completely lost.  Not that the words with accented
characters are completely unhyphenated, but only some of them are.

I am attaching my regi-il5.tex and a test file (and its DVI form, to
save you from tinkering with your setup just to see the problems
I describe below).  Please note that I have tried many variations of
both the macro I call (such as \definecharacter, etc.), and the way
I type the substituted accents (\c c vs. \ccedilla).  Here are the
problems:

  - Even though the hyphenation for a\u{g}ra is correct, I cannot
    redefine it using ð (\u{g} in Latin5 encoding).  I can redefine it
    using \u{g}, but then I lose all of its hyphenation.

  - Words which have one of \i (dotless i) or \.I  characters are not
    hyphenated at all.  This is most problematic in the second column
    of the sample text.

  - Some of the hyphenations are wrong.  For example da-\u{g}-lar, it
    should be da\u{g}-lar.  Similarly ta-\c{s}-lar should be
    ta\c{s}-lar.  Also \c{c}o-rap\c{c}\i should have an hyphen before
    the second ccedilla (though I have an intuition that it is due to
    the right syllable being short, can it be?).

I am also attaching a similar file for LaTeX (again, with related DVI
output).  Please notice how words containing dotless i characters are
correctly hyphenated.  Since ConTeXt and LaTeX share the same
hyphenation patterns, I cannot see why they are generating different
outputs.  From texexec's output:

  language       : patterns 2:2-tr-2 3:2-tr-2 4:2-en-2 5:2-uk-2 6:2-de-2
2-fr-2 9:2-it-2 2-nl-2 loaded

Possible clash with hyphenation pattern files?  Or do I have to
explicitly state that I want tr hyphenation in my test file?  (tr is
the default language.)

What can be the source of my problems?  I am willing to provide you
any information regarding my TeX/ConTeXt/LaTeX setup you may need.

Once I have all going, I will send everything to Hans Hagen to be
included in the future ConTeXt releases.

By the way, I am a total newbie with TeX.  This can be the source of
all my problems ;)  Also, tomorrow is my birthday, so I am looking
forward to seeing a few presents, such as a fix ;)

Thanks.
Regards,

PS. In one of Hans Hagen's earlier messages to ntg-context list (dated
around 1998), he mentions your name as the language guru, that is why
I am sending this to you.  Also I am having problems with the address
I used when subscribing to ntg-context list, and I do not want to
delay my ConTeXt adventure anymore.  I hope I am not being rude.
