In general, Lynx translates letters from document charset to display charset.
If document charset is not specified or not recognized by Lynx, we fall back
to different assumptions below, read also lynx.cfg for info.
UCLYhndl_for_unspec - assume this as charset for documents that don't
specify a charset parameter in HTTP headers or via META
this corresponds to "assume_charset"
UCLYhndl_HTFile_for_unspec - assume this as charset of local file
this corresponds to "assume_local_charset"
UCLYhndl_for_unrec - in case a charset parameter is not recognized;
this corresponds to "assume_unrec_charset"
UCLYhndl_HTFile_for_unrec - the same but only for local files,
currently not used.
current_char_set - this corresponds to "display charset",
declared in LYCharSets.c and really important.
All external charset information is available in so called MIME format.
For internal needs Lynx uses charset handlers as integers
from UCGetLYhndl_byMIME(). However, there is no way to recover
from user's error in configuration file lynx.cfg or command line switches,
those unrecognized MIME names are assumed as LATIN1 (via safeUCGetLYhndl...).
