PAText supports Persian and Arabic text in Qt applications
Persian and Arabic Text (known as "PAText") fixes problems with glyphs in some environment which does not support the "FA" and "AR" keyboard layouts by default. The class acts like a translator for pointing Persian characters to the correct style in the UTF-8 character set.
Applications
Useful as a solution for displaying Persian and Arabic texts in applications written in Qt for WindowsCE/Mobile platforms as well as creating Persian or Arabic virtual keyboards.
