If you look at the commentary on the related functions, you can see
that
I was heading in the direction of getting them out of the coding-system
business as much as possible. Instead, I'd just unify (or de-unificate,
in the case of Han sets) *charsets*, and let some other facility handle
choosing an appropriate coding system. Ie, not caring whether non-Latin
charsets were present or not was more or less by design.
Well, “less,” because that wasn’t what you said in the docstrings :-) . Your
commentary is also full of things like:
;; #### I see nothing useful to be done with APPEND.
;; FILENAME, VISIT, or LOCKNAME could be used to default the coding system,
;; but this would conflict with the semantics of `write-region'.
;; #### The efficiency of this function can clearly be improved.
;; #### This function should be set up to call the check functions in a
;; condition-case, and call out to error handlers. Then tests could be
;; written more easily.
which is only readable in the event that you’re modifying the package and
have looked at the details of the implementation, rather than just the
interfaces. I didn’t read the commentary in detail as a result, since I was
interested in using the package.
Unfortunately, I don't recall how far that program proceeded (I
didn't
The technical problem is that non-Latin charsets were inconceivable to
latin-unity. The following patch adds a signal that tells latin-unity
"whoa, hands off!" Unfortunately, this means that you can't remap a
region that contains non-Latin characters *at all*; you need to
restrict attention to Latin-only regions.
That’s fine, I think; previously, remapping a region with non-Latin
characters would do something other than the docstring would lead you to
expect. And one can restrict attention to Latin-only regions with a
combination of skip-chars-forward, char tables, and the
latin-unity-character-sets variable.
The recoding functions may need similar treatment, I haven't
looked yet.
I'm almost sure this will cause annoyance to somebody, but most such
somebodies *probably* can just turn off latin-unity.
Hmm, I actually doubt it, but we’ll see.
