Little endian to big endian UTF-16 conversion
Posted: Fri Sep 13, 2024 12:24 pm
Receiving a file in UTF-16 little endian from a Windows on an as/400 ( formerly known as ) gives a practical problem
that the as/400 only can handle UTF-16 big endian ( CCSID(1200) ).
As far as I can see UTF-16 little endian ( CCSID(1202) ) is not supported here.
The question is: Is it enough to create a program that reads 2 bytes from the UTF-16LE file, swaps the bytes and writes
the 2 bytes to a file that then should be in UTF-16BE format. Of course reading and writing if pure binary.
Something like this in pseudo code
And then finally change the CCSID on UTF-16BE to 1200
that the as/400 only can handle UTF-16 big endian ( CCSID(1200) ).

Code: Select all
open UTF-16LE input binary mode
open UTF-16BE output binary mode
read 2bytes from UTF-16LE
dow not eof(UTF-16LE)
swap(2bytes)
write 2bytes to UTF-16BE
read 2bytes from UTF-16LE
enddo
close UTF-16LE
close UTF-16BE
