Summary: strip on chr(0x1f) different with unicode

Initial Comment:
chr(0x1f) gets stripped from Unicode strings, but not 
from regular strings.  I don't believe either should strip 
it.

Python 2.3.1 (#47, Sep 23 2003, 23:47:32) [MSC 
v.1200 32 bit (Intel)] on win32

>>> sd = chr(0x1f)
>>> sd.strip()
'\x1f'
>>> unicode(sd).strip()
u''

The problem is that "\x1f" (UNIT SEPARATOR) is considered a
space in str.isspace(), but not in unicode.isspace():
>>> u"\x1f".isspace()
True
>>> "\x1f".isspace()
False

For str, isspace() from the OS is used, but for unicode
iswspace() or the unicode database is used.
