Eudora _does_ display using any ISO-8859 character set (e.g. Latin-1),
each of which defines 256 characters, enough for any one "Western" language
(some of these cover a group of related languages), but it does _not_
understand multi-byte "characters" of the UTF-8 character encoding scheme,
which includes many thousands of "characters" from all languages combined,
by means of the use of multi-byte characters as necessary -- in UTF-8,
ascii characters up to value 127 are normally left alone, as single bytes,
hence only "accented" characters and special "curly quotes" etc.
become multi-byte sequences within most "Western" languages.
A third-party plugin is available which replaces some multi-byte characters
with near equivalents from ISO-8859-1, making them more displayable by Eudora;
it's advisable to pay careful attention to the included instructions and settings:
