Hi,
I have a regular expression test in a script. When a unicode character
get tested in the regex it gives an error:
UnicodeError: ASCII decoding error: ordinal not in range(128)
Question: Is there a way to test a string for unicode chars (ie. test
if a string will throw the error cited above).
Like:
if unicode string:
print 'string's line #'
else:
process the string
How do I do "if unicode string" cited in pseudo-code above?
Thanks, still using Python 2.1 5 2323

yes there ist :)
>>isinstance(u" a", basestring)
True
>>isinstance(u" a", unicode)
True
>>isinstance("a ", unicode)
False
>>isinstance("a ", str)
True
>>isinstance(u" a", str)
False

How about :
if ord(max(thestri ng)) >= 128:
print 'whatever you want'

Sure:
try:
s.decode("ascii ")
except UnicodeError:
print 'string's line #'
else:
process the string
Notice that you get a *decoding* error, so you are not testing
Unicode characters, but byte strings.

As Martin pointed out: you are *not* using unicode...
Question: Is there a way to test a string for unicode chars (ie. test

There is but this is not your problem and if it was it wouldn't be the
right solution.
Read http://www.amk.ca/python/howto/unicode. You should at least have
a minimal understanding of unicode before trying to use unicode.

If I use "re.UNICODE " like: m = re.match(r"\w+" , s, re.UNICODE)
then it seems to fix my problem. Trying to read as much as I can on
unicode.... This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I'm sure this is a very simple thing to do, once you know how to do it, but
I am having no fun at all trying to write utf-8 strings to a unicode file.
Does anyone have a couple of lines of code that
- opens a file appropriately for output
- writes to this file
Thanks very much.

I have not been able to find a simple, straight forward Unicode to ASCII

Is that because such a function does not exists or do I overlook it?
I found Encoding.Convert, but that needs byte arrays.

Hello, everyone.
I have a problem when I'm processing unicode strings. Is it possible
to get the 8bit-string representation of any unicode string?
Suppose I get a unicode string:
a = u'\xc8\xce\xcf\xcd\xc6\xeb';
then, by
a.encode('latin-1');
I can get the 8bit-string representation of it, that is, the physical

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
