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?
