Graph stats doesn't support utf8 characters

[Quentin Estoppey]

In stats_chart.php, you have to add utf8_decode functions for graph titles and lables. Otherwise ther aren't dispayed correctly.
Ex lines 70-80 :
$graph_title = utf8_decode(ev_gettext("Issues by Priority"));
$graph_title = ev_gettext("Issues by Assignment");
$graph_title = utf8_decode(ev_gettext("Issues by Category"));

$labels[] = utf8_decode($label) . ' (' . $count . ')';

using utf8_decode() assumes your data can be presented in latin1 (iso8859-1) charset.

correct fix would be to teach jpgraph utf8 data, not convert data to latin1

otoh, it would work fine if you just put unicode compatible ttf font files to lib/jpgraph/ttf dir:

verdana.ttf
verdanabd.ttf

(just those filenames, fonts themselves can be other)

[Elan Ruusamäe (glen666)]

can't do much here, other than suggest using unicode .ttf font
