I am making a keyboard layout in xkb for Punjabi language. The default ones are outdated. In windows I could assign a keyboard key to a sequence of Unicode characters. But in xkb I think I cannot. But in some Arabic layouts it has been done. I want the mapping to be Punjabi specific only and do not want to ruin my default English mapping. e.g. I have assigned " ਾ"(sounds like 'aa',Unicode 0A3E) to 'w' and want to assign 'W' to " ਾਂ"(sounds like 'aan',Unicode 0A3E+0A02)", which is composed of two Unicode characters " ਾ"(Unicode 0A3E) + " ਂ"(Unicode 0A02).
Can anyone help me,please?
