   The right place to discuss this is emacs-devel, not here.

Emacs provides var ‘find-word-boundary-function-table’, used in
Capitalized Words Mode (see lisp/progmodes/cap-words.el).  There are
several "subword" modes, Thai Word Mode (lisp/language/thai-util.el),
etc.

Perhaps some ideas and techniques there can be used in this context by
normal users (with adventurous spirit :-D) here, as well.
