Well, that part was fine. (:
You could also write a multibyte-capable version
like so:

map_1(F, Bin) ->
  {C, Rest} = F(Bin),
  [C | map_1(F, Rest)];
map_1(F, <<>>) -> [].

where e.g. F could call:

cp037_to_iso8859_1 (<<129:1, Rest/binary>>) -> {97,Rest}; % a
...

Then, your conversion fun could select as many bytes
as it needs to.

BR,
