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

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.

Best way to get yourself into trouble.

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.

HTH,

How about:

 if ord(max(thestring)) >= 128:
 print 'whatever you want'

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

Test for a unicode string

[goldtech]

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
