Convert two source files to UTF-8

The files in this commit have previously contained text encoded as Windows-1252 (commonly mistaken for latin1/ISO-8859-1), in ways that present invalid UTF-8 bytes.

This commit converts the encodings to UTF-8, which resolves the encoding issues. While the whole-posts document could be argued to be intentionally Windows-1252, there was no obvious evidence that this was more than an historic legacy. The JavaScript file, however, definitely ought to be UTF-8.
