UCS-2 would be very easy to support as it's a strict subset of UTF-16.
I think we should focus on the library design first before deciding
which encodings to include though.
>The external encoding must be specifiable as a runtime selection.
Agreed. One of the most important use cases I see for this library
would be reading an external file that's encoded in a manner not known
until runtime - e.g. an xml file. Having to specify source encodings
at compile time wouldn't be useful.
Specifying destination encodings at compile time does seem useful
though - i.e Read whatever is in this file and encode it into UTF-16.
The destination encoding would probably have to be known anyway to
pass the data to APIs.
> I would definitely encourage breaking the work up into smaller chunks.
I think one chunk should be routines that, given a sequence of bytes,
determine that possible encodings used to encode those bytes (looking
at bytes used and any BOM that might exist).
This could be overloaded/extended by users for XML and other formats
that can explicitly define their encoding (e.g. the encoding attribute
on XML declarations).
