Because, for whatever reason, Adobe Reader doesn't touch Æ or æ.

You could also argue that the current pdftotext behavior for these math symbols
is correct because even if Reader changes them into Greek letters, the
characters are actually encoded in the document as math symbols.  I'm
ambivalent because I expect someone will complain either way.

The original description says that search doesn't work because of the
symbol/letter confusion.  I assumed Govert meant using the search feature in,
for example, Evince.  The way search works, TextPage::findText calls
unicodeNormalizeNFKC and searches through the normalized text.  These two
patches cause unicodeNormalizeNFKC to convert the math symbols to letters and
the search matches.  This works for Evince, anyway.  I haven't tested it with
Okular.
