How does using a True Type Font (*.ttf) affect Unicode support in PHPLOT?

Using a True Type Font (*.ttf) in PHPLOT can affect Unicode support because not all True Type Fonts support Unicode characters. To ensure proper Unicode support, you should choose a True Type Font that includes the Unicode character set. Additionally, you may need to specify the font encoding in your PHPLOT configuration to ensure that Unicode characters are displayed correctly.

$plot = new PHPlot();
$plot->SetDefaultTTFont('path/to/unicode.ttf');
$plot->SetEncoding('UTF-8');
