[tex-k] Incompatibility between WEB and C versions of "ovp2ovf"

I'm not familiar with the issue. Probably (MAP ...) part is not necessary
in the case where character code is not remapped.
You can confirm that (MAP ...) part is present for ovp2ovf if character
code is remapped.

I don't know details, but 'o...' or 'wo...' are utilities for
Omega/Aleph, a UTF-16 engine.  XeTeX also uses otangle.

No, "oweave" is not necessary, since WEB syntax is not changed.
For example, you can compile as follows:
weave otangle.web
tex otangle.tex
