It could be done, but why hard-code in C what can be done in Lisp?
The advantage would be that more people will understand the code and
changing it does not require rebuilding Emacs.

I don't understand why: we have map-char-table to do that easily and
elegantly.

I don't think modifying entries in a char-table creates a new one. It
just modifies entries in the existing one. Perhaps Handa-san could
comment on that.

The information I propose to change is used only for reordering
characters into visual order. I'm talking about the Bidi_class
attribute of the characters. No other attribute needs to be changed.
And the change will be temporary; toggling the feature off will
restore the original types.
