Hi,
Using Python 2.7 on Linux, presumably? It'd be better to be explicit.
I am trying to use a program called MeCab, which does syntax analysis
on Japanese text.
It is generally nice to give a link when asking about 3rd party
software. https://code.google.com/p/mecab/
In this case, nearly all the non-boilerplate text is Japanese ;-(.

and the problem with bytes is that they can have any encoding.
In Python 2 (indicated by your print *statements*), a byte string is
just a string.
and if I try to print it, it prints question marks for almost
all characters. However, if I try to use .decide, it throws an error.
Here is my code:
What do the MeCab docs say the tagger.parse byte string represents?
Maybe it's not text at all. But surely it's not utf-8.

MeCab: Yet Another Part-of-Speech and Morphological Analyzer
followed by Japanese.
#!/usr/bin/python
# -*- coding:utf-8 -*-
import MeCab
tagger = MeCab.Tagger("-Owakati")
text = 'MeCabで遊んでみよう！'
Parts of this appear in the output, as indicated by spaces.
'MeCabで遊 んで みよ う！'
result = tagger.parse(text)
print result
result = result.decode('utf-8')
print result
And here is the output:
MeCab �� �� ��んで�� �� ��う！
Python normally prints bytes with ascii chars representing either
themselves or other values with hex escapes. This looks more like
unicode sent to a terminal with a limited character set. I would add
print type(result)
to be sure.
Traceback (most recent call last):
File "test.py", line 11, in <module>
result = result.decode('utf-8')
File "/usr/lib/python2.7/encodings/utf_8.py", line 16, in decode
return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 6-7:
invalid continuation byte
------------------
(program exited with code: 1)
Press return to continue
Also my terminal is able to display Japanese characters properly. For
example print '日本語' works perfectly fine.
