 Chinese legend labels |

Hi everybody,
I have an issue displaying Chinese characters in an XY-Chart legend label.
I have already made sure to encode everything in UTF8 (Russian labels work fine) and I assume square boxes instead of gibberish means that it is more of a font than an encoding issue, right? The rest of my software displays Chinese characters without a problem.
This is how I add the legend (C++):
c->addLegend(75, 5, false, "arialbd.ttf", 8)->setBackground(Chart::Transparent);
I also tried not setting any specific font and size:
c->addLegend(75, 5, false)->setBackground(Chart::Transparent);
Both don't seem to work.
See attached screenshot.
What am I doing wrong?
Thank you for your input.

Hi David,
The square character means the encoding is correct, but there is no such character in the font used (arialbd.ttf in your code).
To solve the problem, please use a font that contains Chinese characters. You can specify multiple fonts if you like. For example:
// Use the simsun.ttc font. (This assumes the font exists on the computer.)
c->addLegend(75, 5, false, "simsun.ttc", 8)->setBackground(Chart::Transparent);
or
// Use the arial bold font. If the character is not supported, try the simsun.ttc font with boldening.
c->addLegend(75, 5, false, "arialbd.ttf;simsun.ttc bold", 8)->setBackground(Chart::Transparent);
Hope this can help.
Regards
