New submission from Bob Kline <bkl...@rksystems.com>:
- UNWANTED = re.compile("""['".,?!:;()[\]{}<>\u201C\u201D\u00A1\u00BF]+""")
+ UNWANTED =
re.compile("""['".,?!:;()[\]{}<>\\u201C\\u201D\\u00A1\\u00BF]+""")
The non-ASCII characters in the original string are perfectly legitimate str
characters, using valid standard escapes recognized and handled by the Python
parser. It is unnecessary to lengthen the string argument passed to
re.compile() and defer the conversion of the doubled escapes for the regular
expression engine to handle.
