Actually, the results are inaccurate or even incorrect, at least in
some cases. Here's one case where the results are wrong:
emacs -Q
C-h h
C-u 411 M-g c
C-u C-x =
You will see towards the end of the *help* buffer:
Composed with the following character(s) "്" using this font:
harfbuzz:-outline-Kartika-normal-normal-normal-serif-13-*-*-*-p-*-iso10646-1
by these glyphs:
[0 1 3384 337 12 0 12 9 0 nil]
from these character(s):
സ (#xd38) MALAYALAM LETTER SA
് (#xd4d) MALAYALAM SIGN VIRAMA
ക (#xd15) MALAYALAM LETTER KA
ാ (#xd3e) MALAYALAM VOWEL SIGN AA
The added list of characters seems to imply that 4 characters were
composed at buffer position 411. But actually only the first 2 of
them were composed, as clearly see from the line starting with
"Composed with" above.
A similar problem happens at buffer position 413 of HELLO. And at
position 872 you can see an even more stark example: instead of 2
characters, we show 8(!).
Can this please be fixed?
