I'm seeing another problem with prog-prettify-symbols, but I haven't
filed yet a new bug because for now I can only reproduce it with my
setup.
Sometimes `lambda' gets correctly prettified, and sometimes no (see
attached image).
This is the char info for the correctly prettified lambda:
position: 55719 of 81109 (69%), column: 11
character: l (displayed as l) (codepoint 108, #o154, #x6c)
preferred charset: iso-8859-15 (ISO/IEC 8859/15)
code point in charset: 0x6C
script: latin
syntax: w which means: word
category: .:Base, L:Left-to-right (strong), a:ASCII,
l:Latin, r:Roman
to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
buffer code: #x6C
file code: #x6C (encoded by coding system iso-latin-9-unix)
display: composed to form "lambda" (see below)
Composed with the following character(s) "ambda" by the rule:
(?λ)
The component character(s) are displayed by these fonts (glyph codes):
λ: uniscribe:-outline-DejaVu Sans
Mono-normal-normal-normal-mono-13-*-*-*-c-*-iso10646-1 (#x301)
See the variable `reference-point-alist' for the meaning of the rule.
Character code properties: customize what to show
name: LATIN SMALL LETTER L
general-category: Ll (Letter, Lowercase)
canonical-combining-class: 0 (Spacing, split, enclosing, reordrant,
and Tibetan subjoined)
bidi-class: L (Left-to-Right)
decomposition: (108) ('l')
mirrored: N
uppercase: 76 (L)
titlecase: 76 (L)
There are text properties here:
charset iso-8859-15
composition [Show]
face font-lock-keyword-face
fontified t
and this is the info for the incorrect one:
position: 55396 of 81109 (68%), column: 11
character: l (displayed as l) (codepoint 108, #o154, #x6c)
preferred charset: iso-8859-15 (ISO/IEC 8859/15)
code point in charset: 0x6C
script: latin
syntax: w which means: word
category: .:Base, L:Left-to-right (strong), a:ASCII,
l:Latin, r:Roman
to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
buffer code: #x6C
file code: #x6C (encoded by coding system iso-latin-9-unix)
display: composed to form "lambda" (see below)
Composed with the following character(s) "ambda" by the rule:
(?l ?a ?m ?b ?d ?a)
The component character(s) are displayed by these fonts (glyph codes):
l: uniscribe:-outline-DejaVu Sans
Mono-normal-normal-normal-mono-13-*-*-*-c-*-iso8859-1 (#x4F)
a: uniscribe:-outline-DejaVu Sans
Mono-normal-normal-normal-mono-13-*-*-*-c-*-iso8859-1 (#x44)

a: uniscribe:-outline-DejaVu Sans
Mono-normal-normal-normal-mono-13-*-*-*-c-*-iso8859-1 (#x44)

Adding a char before it or otherwise modifying the line makes the
lambda be correctly prettified again. Weird.
