bug#3533: 23.0.94; Availability of unicode glyphs on Win XP

I'm using pretest Emacs 23.0.94 on both platforms W2k SP4 and XP SP3. By

,----
| M-x describe-input-method RET rfc1345 RET
`----

I get the full list of RFC1345 mnemonics.

On W2k almost all glyphs (aside from a couple of octal sequences) are
displayed. On XP, however, I get a lot of blank boxes there, just as if
all those glyphs were not included in the font.

Both Emacsen have identical settings and I did not make any changes to
the font variables ('fixed-pitch' points to Family:Monospace).
