That's because ?ß has no upper case, so lowercasep in src/buffer.h
return 0.

(Actually in Unicode, ?ß does have a capital variant, ?ẞ, but while
lowercasing ?ẞ maps to ?ß, uppercasing ?ß actually maps to "SS".)

Hi,

in scratch-buffer, emacs -Q,

cursor at end of line at LATIN SMALL LETTER SHARP S,

evaluating the form below results in "0", i.e. no move

(skip-chars-forward "[:lower:]")

AFAIU [:lower:] doesn't recognise that char

C-u C-x =
says:

         character:  (223, #o337, #xdf)
preferred charset: iso-8859-1 (Latin-1 (ISO/IEC 8859-1))
        code point: 0xDF
            syntax: w 	which means: word
          category: .:Base, h:Korean, j:Japanese, l:Latin
       buffer code: #xC3 #x9F
         file code: #xC3 #x9F (encoded by coding system utf-8-unix)
           display: by this font (glyph code)
     xft:-unknown-DejaVu Sans 
Mono-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1 (#xA1)

Character code properties: customize what to show
   name: LATIN SMALL LETTER SHARP S
   general-category: Ll (Letter, Lowercase)

There are text properties here:
   fontified            t

thanks all,
