Is there any way to find the position of the “tip” of the arrow character in Unicode?
For example, I have ↱ and you want to find the position ">" so that I can draw a character at the corresponding y position in my widget.
It depends on the font.
You can try blitting the glyph using a library such as FreeType (not sure if Qt has glyph blenders) in the image buffer, and then find the rightmost pixel, which should be the end.
