No, it isn't...

The HTLoadedDocumentCharset() returns only the original charset, and only
if it was explicitly given.  Since the document has been translated at the
point when it is mailed, this will be wrong if the display character set
differs from the original charset.

This would already give the wrong result in Lynx code without chartrans,
if the document was labelled with "charset=iso-8859-1" and 8-bit
characters were translated to some display character set where they are
different.

But if you change it (make it like for non-source mail), a charset given
in a META tage which was right before may now become wrong... Sigh.
Well there are good reasons for keeping meta-information *outside*
of a document...
