24.2; Display script symbol name when calling `describe-char' |
Date: |
Wed, 13 Feb 2013 01:30:41 +0800 |
Please refer to this thread:
https://lists.gnu.org/archive/html/help-gnu-emacs/2013-02/msg00138.html
Sometimes the script name symbol of a character is more important than
its charset. For example, you'd like to use `set-fontset-font' to set a
proper font specifying its script as target, rather than specifying its
charset, which usually is unicode.
In addition, as unicode family is a common charset, the "preferred
charset" displayed by `describe-char' seems not quite useful. In
contrast, script makes more sense. For example, script 'han tells me this
is a CJK character and 'greek tells me this is a greek letter, while
charset often tells me nothing.
Therefore, I suggest display the script name symbol as well when calling
`describe-char'. So that we can press [C-u C-x =] to get it.
I also wrote a simple patch for this.
Besides, I hope there is a handy function called
`list-character-scripts', just like `list-character-sets'. It's a really
simple function: just return
(char-table-extra-slot char-script-table 0).
I believe this function will make script name symbols less confuse.

Thank you. I installed this into trunk so it'll be in Emacs 24.4.
I also replaced char-table-range with aref which works as well here.
