For FT_UINT_STRING obviously ENC_[BIG|LITTLE]_... would be needed for all.

However, I can understand the approach of always specifying an
endianness to be consistent with other usage. After all, we're already
using ENC_NA for FT_BYTES, FT_NONE & etc.

Thoughts ?


Ok: I'd like to get the work done for FT_STRING, ... (and having not received much comment on this)

I propose to do the following for
the FT_STRING, FT_STRINGZ, FT_UINT_STRING "encoding" parameter:

Essentially: Specify a character encoding but specify endianness only where relevant.

Conversions:
1.  For other than FT_UINT_STRING, remove all existing True/1/FALSE/0
    & ENC_NA/ENC_BIG_ENDIAN/ENC_LITTLE_ENDIAN;

2.  If there's no character encoding (ENC_ASCII, ...) specified
    then use ENC_ASCII.

    As Guy noted re the choice of character encoding:

I've no idea of which is "worse" (or how to decide) so I picked ENC_ASCII.

I'll hold off doing any changes until tomorrow to wait for any comments.
