Subject: How does Cygwin handle non-Latin1 man pages? (move to UTF-8?)
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Hi,

As far as I see it, on Cygwin it is assumed that man pages are encoded 
in Latin-1 (ISO-8859-1).
For instance the man pages of vim.

/usr/share/man/fr/vim.1.gz is encoded in Latin-1.

$ export LANG=fr_FR.UTF-8
$ man vim

This will show the French man page correctly. Latin-1 is converted to UTF-8.

For the Russian translation of the vim manual I see two files:
/usr/share/man/ru.UTF-8/man1/vim.1.gz
/usr/share/man/ru.KOI8-R/man1/vim.1.gz


When I type
$ export LANG=ru_RU.UTF-8
$ man vim

I get the English man page, instead of the Russian man page.
I think because there is no /usr/share/man/ru/man1/vim.1.gz present.

When I type

$ export LANG=ru_RU.UTF-8
$ export LANGUAGE=ru.UTF-8
$ man vim

The Russian man page is displayed, but all Russian characters are 
wrongly displayed.
I think because it is assumed the man page is in Latin-1.

To get a correct display of the Russian man page I need to change 
/etc/man.config
I change the line with NROFF to:
NROFF         /usr/bin/preconv | /usr/bin/nroff -c -mandoc 2>/dev/null

Now the Russian man page displays correctly, but now all the Latin-1 
pages display wrongly.

So I undo my change in /etc/man.conf


On Linux the trend is to convert all man pages to UTF-8 encoding.
Will Cygwin follow this trend?

regards,
