Jython: How to import escaped Unicode and export utf-16?

[Maurice Bauhahn]

Thank you, Martin, you have been patient and persistent. I've finally
started to sort out some of my problems. It appears that I confused \x
and
\u while frustratedly trying to move forward;-) Today I finally started
to
have some progress. My problem was that importing text files with
unicode
escapes really does require codecs (importing text files, not Python
scripts).


(UNIESCAPE_encode, UNIESCAPE_decode, UNIESCAPE_streamreader,
UNIESCAPE_streamwriter)=codecs.lookup('raw-unicode-escape')

onea =
UNIESCAPE_streamreader(codecs.open('H:\\jy\\encodings\\KSCIIOne.txt','r','raw-unicode-escape'))

oneencoding = onea.read()

This stream I can then read line by line by using:

for encodingline in oneencoding.split('\n'):

My confusion was the apparently redundant use of raw-unicode-escape
(which
allows reading \u1780 type of characters).

Export (I decided to use the more easily readable utf-16 encoding)
similarly requires:

(UTF16_encode, UTF16_decode, UTF16_streamreader, UTF16_streamwriter) =
codecs.lookup('utf-16')

outdocument = UTF16_streamwriter(
codecs.open('h:\\jy\\outtest.txt','wb','utf-16' ))

I trust this helps someone else who confronts similar problems;-)

Cheers,

Maurice
