Dear Jason,

Okay, I understood.

Now I have confirmed that w32_font_match() in w32fns.c has been
modified to encode the font name. Thank you for your support.

Unfortunately, however, the fix would not completely solve the
problem. It does solve the issue on font-name matching, but not on
fontset-name matching.

Please consider the following case:

   "-*-MS ゴシック-normal-r-normal-*-12-*-*-*-C-*-fontset-test,
japanese-jisx0208:-*-MS ゴシック-normal-r-*-*-12-*-*-*-c-*-jisx0208-sjis,
katakana-jisx0201:-*-MS ゴシック-normal-r-*-*-12-*-*-*-c-*-jisx0208-sjis"

      => ("-*-MS ゴシック-normal-r-normal-*-12-*-*-*-c-*-fontset-test"
              "-*-courier new-normal-r-*-*-13-*-*-*-c-*-fontset-standard"
  (query-fontset "*test*")
      => "-*-courier new-normal-r-normal-*-12-*-*-*-c-*-fontset-test"

  ;; try choosing a fontset interactively.
  (setq w32-use-w32-font-dialog nil)
  Using menu bar: Options -> Set Font/Fontset
      error--> Invalid fontset: nil

  ;; test some other functions.
  (list-fontsets nil)
      error--> Invalid fontset: nil
  (fontset-plain-name (query-fontset "*test*"))
     error--> Invalid fontset: nil

Apparently the multibyte string in the first font-pattern is doing
something bad.

These errors did not occur when I modified
fast_c_string_match_ignore_case(). Maybe there are some other callers
that need to be fixed -- possibly in fontset.c?
