Hello Fabrice


Thanks for your follow up.  I saw your picture and I am choked to see 
that TeXmacs looks completely awful.  I include a picture of my TeXmacs 
installation, running the first screen.  It looks good, but lacks the 
images of the pair of bulls either the spanish or the english version 
(from Help -- About -- Welcome original message).  You can see it in the 
following web address:

I am using TeXmacs 1.0.7.10 on Windows XP SP3 Spanish, with spanish locale.

TeXmacs ran well, except that the only fonts that works are Roman, 
Concrete and Deja Vu (I have this last font installed in windows/fonts 
directory and also in MikTeX directory).  Therefore the situation is at 
least aceptable with respect to a minimum variety on fonts selection.

Neither works the invocation of Asymptote, Maxima, Gnuplot or Graphviz, 
which I have installed in my sistem.  The last year I read somewhere 
that for windows, those sesion scripts doesn't work.  I ignore why and 
if the situation is remediable by an user.

I searched the readme text files in TeXmacs installation for hints about 
the fonts use and found the following reference:

    ----
    GNU TeXmacs uses the following algorithm to find fonts:

    - Look whether the font is in one of directories specified by the 
user paths TEX_TFM_PATH or TEX_PK_PATH.
    - Look whether the font is installed by default in 
$TEXMACS_PATH/data/tfm or $TEXMACS_PATH/data/pk.
    - Look whether the font was already generated in the TeTeX 
distribution (using kpsepath).
    - Automatically generate the font using MakeTeXTFM and/or MakeTeXPK.
    -----

And from 'compiling TeXmacs' I learned that:

    ----
    From compiling TeXmacs:

    * You have problems with the font system from TeX when running.
      Solution: get a version of TeX with 'kpsepath', 'MakeTeXPK' and 
'MakeTeXTFM'.

    *  TeXmacs runs fine, but certain fonts are not displayed correctly.
        Solution: This problem may have several causes:
      o     You use a recent version (>= 7.3) of RedHat Linux or one of 
its clones. On such systems, the installation of
            TeTeX is bugged and you need to change some permissions in 
order to allow font generation by Metafont.
            As root, type chmod -R a+rw /var/lib/texmf/*
      o    You do not use a standard TeX/LaTeX distribution, such as 
TeTeX (standard distributions come with scripts
            for generating fonts, such as 'mktextfm' or 'MakeTeXTFM'). 
You may either install a more standard TeX/LaTeX
            distribution, or download some pregenerated fonts from 
texmacs.org.
    ----


So, I made the two environmental variables (TEX_TFM_PATH and 
TEX_PK_PATH).  Also, modified by hand the file settings.scm in 
"C:\Documents and Settings\Denis\Datos de programa\TeXmacs\system", 
adding the following content:

    ----
    (VERSION "1.0.7.10")
    (KPSEPATH "false")
    (KPSEWHICH "C:\Archivos de programa\MiKTeX 
2.9\miktex\bin\kpsewhich.exe")
    (MAKETFM "C:\Archivos de programa\MiKTeX 
2.9\miktex\bin\miktex-maketfm.exe")
    (MAKEPK "C:\Archivos de programa\MiKTeX 
2.9\miktex\bin\miktex-makepk.exe")
    (TEXHASH "C:\Archivos de programa\MiKTeX 2.9\miktex\bin\texhash.exe")
    (TFM "C:\Archivos de programa\MiKTeX 2.9\fonts\tfm")
    (PK "C:\Documents and Settings\Denis\Configuración local\Datos de 
programa\MiKTeX\2.9\fonts\pk")
    (PFB "C:\Archivos de programa\MiKTeX 2.9\fonts\type1")
    (DPI "600")
    (EC "true")
    ----

Originally the file contained the value "false" or "{}"for almost all 
the variables and '(EC "false")'.

Since I suspected that TeXmacs wasn't able to find my MiKTeX 
installation.  I searched for kpsewhich, maketfm, makepk and texhash.  
Maketfm and makepk are named differently and this could be an issue with 
TeXmacs.

As a result, TeXmacs made a clear effort to build the fonts, but for 
some unknown reason the process failed.  I suspect that this is related 
to the lack of kpsepath in MikTeX.

After this, I was determined to found and install TeTeX, but is an 
abandoned version without an addres to download it from for windows.  
LaTeX live, informs that can't be two LaTeX version installed because 
the environmental variables conflict each other.

After this failure, I searched for a LaTeX package to print font 
characters tables, but the size of the effort is big and also, the font 
name in LaTeX, although documented with the Karl Berry naming scheme, is 
really hard to use to construct the LaTeX instructions to build fonts 
tables.  Since I have a full MiKTeX instalation, I made a directory 
listing, and found that I have 512 font files.  For the mean time I 
haven't been able to find a programatic way to declare every font and 
instruct pdfLaTeX to generate the font table, which was my hope to 
produce the font metrics files that TeXmacs uses.

I also have the idea that the font encoding tables that TeXmacs uses to 
access the characters with diacritical marks, those of Latin 1 in TeX 
encoding or ISO-8829-1, perhaps have some problem, but I haven't 
inspected in educated manner those tables because I still don't know how 
this encodings works.

What I have found so far is that the mechanism for building fonts, fails 
in Windows XP SP3.  I don't now if this situation is specific to XP or 
to Windows.  I even installed TeXmacs in a path without spaces, without 
solving the fonts problem.   But the hints indicates me that is related 
to an inability to locate and use MiKTex.

The solution of installing prebuild fonts, does not work well also for 
me.  There are two files available.  One of them is in TeXmacs web 
site.  The other one which I did not retained the web address where I 
found it, I believe is residing in git hub.  This is more complete, but 
comes from a Linux box and uses 'make' to build and install and wasn't 
able to use it effectively.

I installed the font package from TeXmacs web site.  The first time in 
my user directory and the second time in the program directory, without 
a positive result.  The failure of using precompiled fonts with TeXmacs 
indicates me, that the problem to displaying correctly the fonts, 
resides in TeXmacs itself.

I have detected two problems:

    -  TeXmacs does not found the declared font and uses the Roman face 
instead (declared using the menu selecting
        'Document -- Font -- Text font).
    -  TeXmacs does not display correctly characters with diacritical 
marks common in spanish
        (á é í ó ú ü Á É Í O Ú ñ Ñ ¿ ¡) with fonts different from the 
three I mentioned previously.


As you might see, I am still far away to found a solution, but I have 
hope that I will find one.

If you like, both of us can make comparisons of our Windows XP 
installations.  Perhaps your machine lacks some software, environment 
variables or a correct key in the windows registry.


Thanks for your interest,


Denis J Navas
