Yes, it looks great. And yes, the number should be on the right.
Thats the start of the string in hebrew.
Note that if you use Locale::Hebrew, it only works well for unicode
hebrew, whereas most tags are still ISO hebrew. Therefore, I wrote my
own patch which handles both unicode hebrew and iso hebrew. (Thanks
for the note about Locale::Hebrew - it solved my problem). I'm not a
perl developer so my code probably sucks, but here it is anyway. I put
it in Graphics.pm, at the beginning of String(). My code is between the
"Mack" comments.
<code>
sub string {
my $fontname = shift || return '';
my $string = shift || return '';
# Mack
use Locale::Hebrew;
for my $ord (unpack('U*', $string)) {
# Convert ASCII Hebrew to Unicode Hebrew if required.
if ($ord > 223 && $ord < 251) {
require Encode;
$string = Encode::decode('iso-8859-8',
$string);
last;
}
}
$string = hebrewflip($string);
# /Mack
my $bits = '';
</code>
(Sorry about lack of indentation. The forum seems to drop the tabs
upon submitting).
This code seems to produce correct results in all files I checked. The
manual test for ASCII hebrew was added because Encode::decode crashed on
certain unicode strings.
Now, the only problem I failed to solve is the scrolling. When a long
hebrew string needs scrolling, it should start by showing the rightmost
part of the string first, and scroll towards the leftmost part of the
string. I can't find the part that controls scrolling. Is it handled
by the firmware itself ? Any way to change the scrolling behavior as
described here ?
Thanks,
Mack
