I wouldn't use the £ sign directly myself, as I doubt that it is part of
the standard ASCII character set.  I'd use "GBP", or wouldn't use a
symbol at all;  A note elsewhere in the plain text email will suffice in
most cases.

I'm not sure what that would be.  Perhaps some charset decoders are
confused by the £ character and treat it as the start of a multi-byte
special sequence.  I don't know - I'd just avoid its use.

You should never use anything other than ASCII in HTML, and shouldn't
even use the double-quote (") symbol, even though it's part of the ASCII
charset.  All "special" characters should be encoded using either &#999;
or preferably, and where available, entities such as &pound;, &quote; and
especially &amp;, &gt; and &lt;.
