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:]")ß

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

C-u C-x =

        character: ß (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
  general-category: Ll (Letter, Lowercase)

There are text properties here:
