We handle Unicode, but right-to-left text is very, very difficult to implement. I'll change the title from “Usage of non-latin function names and variables”, because we support many non-Latin scripts (Chinese, Japanese), but just not right-to-left reading (Arabic, Hebrew, etc).

Greetings, the issue/request was specifically about function names and variable names (calling a function named رسم, having a variable named نقاط), the RTL issue is not the problem, the code is perfectly readable from left to right when it is mixed rtl/ltr scripts are in use, selecting a "good" font will renders the glyphs correctly (so shaping works fine, function names and variable names are usually one word too). if function names and variable names can be used in chinese and japanese then i guess my request/issue is a false alarm. I will repeat my tests and share findings.
