-----------------------+----------------------------------------------------
The FileHandle PMC is supposed to support different encodings via the
'encoding' method. Currently, this only works for single-byte encodings
and UTF-8, that is UTF-16, UCS-2 and UCS-4 are not supported. UCS-2 and
UCS-4 are fixed-width and should be pretty easy to support, but UTF-16
would need something like the code in src/io/utf8.c. It would be cleaner
to move that logic to the string code. We would only need an additional
function in the encoding vtable that can partially decode incomplete
variable-width strings.
One thing that I don't like is that the 'read' method works on bytes not
on characters. I think this doesn't make sense for multi-byte encodings.
We should also consider to support encodings for Socket or StringHandle
PMCs.
