For rendering _code_, i.e, symbols, yes.  But here we are talking
about comments and strings, which are a different matter altogether:
they are human-readable text, and we should not prevent people from
writing that text using bidirectional scripts.  By contrast, the
probability of someone calling a program symbol by a name with R2L
characters is ... remote at best.

If you want to display one character as another, either 'display' text
properties (with string values) or overlay strings.
