Shift-JIS to UTF-8 conversion

[PyTJ]

Hello everybody,

I need to convert a Japanese Shift-JIS CSV file to Unicode UTF-8.

My machine is a Windows 98 english computer with Python 2.3.4

Any hints?.

I think you do something like this (untested):

import codecs

def transcode(infile, outfile, incoding="shift-jis",
outcoding="utf-8"):
f = codecs.open(infile, "rb", incoding)
g = codecs.open(outfile, "wb", outcoding)

g.write(f.read())
# If the file is so large that it can't be read at once, do a loop which
# reads and writes smaller chunks
# while 1:
# block = f.read(4096000)
# if not block: break
# g.write(block)

f.close()
g.close()

Hello,
I think the answer is basically correct but shift-jis is not a standard
part of
Python 2.3. You will either need to use Python 2.4 where the cjkcodes
are integrated or install them under Python 2.3. The link is
http://cjkpython.i18n.org/

You then also need:
import cjkcodecs.aliases

First, you need to install codecs to support japanese encodings.
Python 2.3.* does not support SJIS by default.

I'll give you two options.

- Japanese Codecs
http://www.python.jp/Zope/download/JapaneseCodecs

http://ftp.python.jp/pub/JapaneseCod...in32-py2.3.exe

- CJKCodecs
http://cjkpython.i18n.org/
http://download.berlios.de/cjkpython...in32-py2.3.exe

If you only need Japanese support, Japanese Codecs might be handy.
On the other hand, CJKCodecs can handle much broader encodings.
Aside from that, starting from 2.4, Python ships with CJKCodecs,
so I'd recomment CJKCodecs without reservations.

Ah, I was fooled --- I tested on Python 2.3, but my packager must have
included the codecs you went on to mention.
