Here's the info from before I shrank the font:

           character: ; (59, #o73, #x3b)
   preferred charset: ascii (ASCII (ISO646 IRV))
          code point: 0x3B
              syntax: <        which means: comment
            category: .:Base, a:ASCII, l:Latin, r:Roman
         buffer code: #x3B
           file code: #x3B (encoded by coding system iso-latin-1-dos)
             display: by this font (glyph code)
       uniscribe:-outline-Courier
New-normal-normal-normal-mono-13-*-*-*-c-*-iso10646-1 (#x1E)

   Character code properties: customize what to show
     name: SEMICOLON
     general-category: Po (Punctuation, Other)

   There are text properties here:
     face                 font-lock-comment-delimiter-face
     fontified            t

And here's the info from after:

           character: ; (59, #o73, #x3b)
   preferred charset: ascii (ASCII (ISO646 IRV))
          code point: 0x3B
              syntax: <        which means: comment
            category: .:Base, a:ASCII, l:Latin, r:Roman
         buffer code: #x3B
           file code: #x3B (encoded by coding system iso-latin-1-dos)
             display: by this font (glyph code)
       
uniscribe:-outline-Arial-normal-normal-normal-sans-11-*-*-*-p-*-iso10646-1
(#x1E)

   Character code properties: customize what to show
     name: SEMICOLON
     general-category: Po (Punctuation, Other)

   There are text properties here:
     face                 font-lock-comment-delimiter-face
     fontified            t

   [back]

For what it's worth, I couldn't reproduce the problem on Windows XP,
using Emacs as of

   commit a52d2b7...

      * simple.el (line-move-visual): If point is stuck moving backwards
      against a display string, temporarily ignore the goal
      column (Bug#3020).

In that case, the output from C-u C-x = was

          character: ; (59, #o73, #x3b)
   preferred charset: ascii (ASCII (ISO646 IRV))
         code point: 0x3B
