This is due to RFCs. Look yourself. The Subject line (when not
in plain ASCII) *must* be encoded to either QP (q-type) or
Base64 (b-type), and the encoding used must be specified
there. Upon receiving, the e-mail reader automatically decodes
it and never shows you the "garbage" it actually is. BTW, TB
always encodes the subject field to B-type (base64), although
RFCs say that this has to happen only in the case when the
*major* part of the Subject: field is non-ASCII... Once more,
look through RFC2047 for the details. It's in plain English:-)
Hence it must be much clearer for you then my own writings:-))

It in fact doesn't matter. Two cases:
1. with ISO-8859-1 it supposedly works this way:
a. Some text in Double-byte language (DBL from now on);
b. Each byte is encoded to ISO-8859-1;
c. The header states "ISO-8859-1";
d. On the receipient's end *his* e-mail reader needn't even to
know that this was in DBL; it just decodes it *from* ISO-8859-1
byte-by-byte... Of course, the sequence of bytes is okay now,
equivalent to what was on the sender's end;
e. Now provided that the system supports DBL (fonts etc.) it just
"glues" each pair of bytes together and displays it OK.
2. with Big5 (or any other double-byte encoding) it works as it
should, look through RFCs (again, RFCs 2045--2048).
So well, now, having wrote all this, I cannot tell you for sure
how it works in the case of TB. What I *do* know is that the
guys using Pegasus with Chineeze use ISO-8859-1 without
any problems (as far as I understood them). Simply Pegasus
doesn't support Big5 or any other bouble-byte encoding
directly.
And another thing: I cannot understand, where [the hell] TB
leads to errors? What happens if you specify ISO-8859-1 as
the default encoding, then modify the X-LAT for ISO-8859-1 to
use the proper font and script? Now if you try to send the
message in DBL to yourself, can you read it? Can somebody
else read it? And why?

Once again, it's just a properly formed MIME Subject line... In
Base64 encoding.
