Hi all,

I've got to escape some unicode text according to the following map:

escape_map = {
     u'\n': u'\\n',
     u'\t': u'\\t',
     u'\r': u'\\r',
     u'\f': u'\\f',
     u'\\': u'\\\\'
}

The simplest solution is to use str.replace:

def escape_text(text):
     return text.replace('\\', '\\\\').replace('\n',
'\\n').replace('\t', '\\t').replace('\r', '\\r').replace('\f', '\\f')

But it creates 4 intermediate strings, which is quite inefficient
(I've got 10s of MB's worth of unicode strings to escape)

You might try

  def escape_text(text):
    return text.encode("string_escape")
