Basically, lat is psf, latu is psfu (currency is replaced by EURO), latv
is pure unicode (currency will not be replaced by EURO symbol, only
unicode EURO are replaced) and latw replaces unicode EURO and currency
by EURO.
Here's a chart, please tell me if it isn't clear enough (I wanted font
support to become exhaustive since many people asked for special
replacement of currency or instead non replacement since they already
use UNICODE, etcetera......)
| Iso encoding | Unicode map | Single | Cross
| within font | included | compatibility | compatibility
-------------------------------------------------------------------
lat9 | y | n | n | lat1 + lat9
-------------------------------------------------------------------
lat9u | n | y | n | lat1 + lat9
-------------------------------------------------------------------
lat9v | y | y | unicode | n
-------------------------------------------------------------------
lat9w | y | y | n | lat1 + lat9
| | | | + unicode
-------------------------------------------------------------------
* lat9 fonts do not include any unicode translation map,
therefore each currency sign will look like euro, what could cause
compatibility problems for files coming from windows computers (cp1252 or
latin1 are "incompatible" with latin9) but the huge advantage is it works
right now with linux.
* lat9u fonts are encoded in a non standard sequence (but
identical to latXu fonts from kbd) compared to the latter, therefore it
brings the same problems with cp1252 and latin1 but the unicode translation
map allows nice chars. for semi graphical applications like Yast, mc or
other ncurses or dialog based programs.
* lat9v encoded in iso official sequence just like lat9 but
with a full fledged unicode translation map, so no currency sign will be
replaced by euro
This avoids export problems if you use pure unicode and a unicode keymap :
each latin9 char. is replaced by the adequate unicode char. and then
displayed what is not only technically elegant but also useless with
"standard" linux console. Very few systems are unicode ready !
Therefore only use lat9, lat9u or lat9v fonts if you know what you are
doing, else you can go with lat9w, the best compromise : you can
be latin9 compatible immediately.
There is no obligation of unicode or whatever, semi graphical chars. are
not messed up and if you feel like trying unicode, latin9 chars are
displayed correctly (only the 0.3% latin9 incompatible chars. from latin1
lack)
You do not need to understand anything to use euro in everyday life, and if
you still hesitate, trust my choice : lat9w.
In order to use lat9-16.psf (or another lat9 .psf), you must supply a
unicode map :
loadunimap lat9.uni
setfont lat9-16.psf
To use lat9w-16.psf (or another lat9u, lat9v or lat9w) :
setfont lat9w-16.psf
