[syslinux] Display borked when loading FONT

[appzer0]

Hello,

I am a happy user of syslinux since 3.x. I've been able to load a font 
to display French accented charecters since then, but it not the case 
anymore, as problems have started to raise with syslinux 5.x.

program : EXTLINUX, ISOLINUX (same behaviour)

In extlinux.conf, the culprit is :

FONT=lat9w16

This font is taken from 'kbd' package, named lat9w-16.psfu. It contains 
a UTF-8 table, usually ignored by extlinux, but maybe it is not the case 
anymore? As usual, extlinux.conf is written using an ISO-8859-1 
encoding, not UTF-8.

All .c32 modules are present in /boot/extlinux/, next to extlinux.conf 
itself. 'extlinux --install' reports no errors.

Result: It displays large vertical white bars and _every_ character is 
borked (but each boot, the same characters are wrongly interpreted the 
same, no random display here, even on the unaccented ones). The Fix is 
easy : comment the FONT= line in, then extlinux is OK, but obviously 
there are no more accents. :-/

I need the French accented characters, namely éèêàâùûôç. At worst, I 
could drop the accented letters but I'd be very sad to.

Tested on syslinux 5.01 and 5.10-pre2. This is the first time ever that 
I run into this problem with syslinux. Please find the extlinux.conf I 
use below.

Thanks!
