You're mildly completely wrong. :) I see the original issue has been resolved,
but I feel like rambling about character encodings. Feel free to completely
ignore the rest of this.
The "�", usually represented as a black diamond with a question mark, is U+FFFD
REPLACEMENT CHARACTER, and it is an actual character (not just a font glyph)
used to replace characters which for whatever reason cannot be correctly
represented.
In this case, it shows up in the browser because the original file contains
non-UTF-8 bytes and so the browser's decoder marks the errors with U+FFFDs. A
hexdump of the content:
5b 6c 61 62 65 6c 6e 61 6d 65 3d 22 f7 e5 e3 20 |[labelname="... |
e4 e1 f0 f7 22 5d 20 7b 20 77 69 64 74 68 3a 20 |...."] { width: |
shows us that there is one byte per "�" character, which hints at that the
browser is reporting non-UTF-8 bytes (as every non-ASCII character is more than
one byte in UTF-8), and converting the first three bytes to binary (11110111
11100101 11100011) shows that this is definitely not UTF-8, as UTF-8 multibyte
sequences consists of "11xxxxxx 10xxxxxx ...".
If the problem actually is lack of _font_ support, then the result is
platform-dependent, but usually either thin-bordered hollow rectangles
(traditional) or thick-bordered rounded squares containing a glyph
representative of the region of Unicode the missing character is from (the
"Last Resort" font).
