Hi!

PUA stands for Unicode Private Use Area, cf. e.g.
https://en.wikipedia.org/wiki/Private_Use_Areas.

I use systematically the PUA characters defined by MUFI,
cf. e.g. https://en.wikipedia.org/wiki/Medieval_Unicode_Font_Initiative.

Recently I made a quick and dirty solution for my own feature request

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=32599

(in a slightly different way than suggested originally).

The files and the documentation are available at
https://github.com/jsbien/unicode4polish in the Emacs-MUFI directory.

Please consider improving and expanding my solution and making it
available as e.g. ELPA or non-ELPA package.

Best regards

Janusz

Thanks.

I may be missing something, but I couldn't find in your Github
repository the infrastructure that could be used to tell Emacs to
interpret arbitrary ranges of PUA codepoints as characters with
certain properties.  Could you please point me to the parts I missed?

You haven't missed nothing. My knowledge of ELisp is too rudimentary for
creating such an infrastructure myself.

However in the documentation I described the procedure needed to tell
Emacs to interpret arbitrary ranges of PUA codepoints as characters with
*names*. It definitely can be extended to handle other properties but I
have not investigated this aspect.

So my repository contains just a proof-of-concept (which also is useful
for me personally).

Thanks, I see the documentation now.

I just noticed a serious bug. Looks like I misunderstood the meaning of
'define-char-code-property'.

I hoped that the second call to it will just supplement the table with
additional values. However looks like the table is recreated from
scratch and in consequence it contains only the MUFI names provided by
me.

I will appreciate your help.

Best regards

Janusz

That's correct, AFAIU.

Why did you need to supplement the table, and which table was it?

I just noticed that I forgot to push 'mufi-name.el' to the repository
(https://github.com/jsbien/unicode4polish/). I have done it now. Below
is a fragment:

--8<---------------cut here---------------start------------->8---

(define-char-code-property 'name
  #^[nil nil char-code-property-table nil #^^[1 0 nil nil nil nil nil
  
[...]

J JJ C K T P H] [A AE YA YAE EO E YEO YE O WA WAE OE YO U WEO WE WI YU EU YI I] [G GG GS N NJ NH D L LG LM LB LS LT LP LH M B BS S SS NG J C K T P H]]]]
  "Unicode character name.
Property value is a string or nil.
The value nil stands for the default value \"null string\").")

--8<---------------cut here---------------end--------------->8---

I expected that the names of the PUA MUFI characters will be added to
the existing Unicode names. However after evaluating it 'describe-char'
doesn't show the names of the Unicode character. I assume the culprit is
'mufi-name.el' but of course the problem can be more complicated.

Regards

Janusz

I think with the current infrastructure you will have to regenerate
uni-name.el such that it includes information both from
UnicodeData.txt and from MUFI.  uni-name.el will then be loaded when
first used.

Alternatively, I think you could use put-char-code-property to modify
the 'name' property of the PUA codepoints you want to use for MUFI.

Thanks for the suggestions.

I have done this and pushed to the repository.
