You changed the subject of the thread and now gmail shows your last
message as the first one in a new thread, so I don't know what you are
talking about exactly. Ok, now I remembered it is about the special
font issue, but please don't change the subject field.

Converting from ansi to utf8 is completely wrong in this case. Do you
know that the definition of ansi changes from computer to computer
resulting in a different end result if you do the conversion in a
russian, chinese, or european computer? Your code simply won't work
everywhere in the world.

Maybe, by coincidence, the ISO Latin 1 to UTF-8 conversion could be
used. You could try that. There is a conversion function
ISO85591ToUTF8 or something similar located in lconvencoding.pas in
the LCL.

In general, take a look in the Unicode characters table:


I am not 100% sure if the 80 to FF characters correspond to Latin 1.
If you are converting from Latin 1 to UTF-8 then the conversion will
only work if they do correspond.

Try converting from Latin 1 to UTF-8 and if it doesn't work write your
own routine.
