In a XML document generated by Trados Translators
Workbench (a TMX V 1.1 Translation Memory), the Unicode
characters U+0001 ("START OF HEADING", see
http://www.fileformat.info/info/unicode/char/0001/index.htm)
and SINGLE LOW-9 QUOTATION MARK (U+201A, see
http://www.fileformat.info/info/unicode/char/201a/index.htm)
produce errors when parsing it from a file with
"xml.dom.minidom".

The first one (0001) produces this output:

Traceback (most recent call last):
  File "G:\_Prog\TMworks\domtree.py", line 7, in ?
    dom=parse(tm)
  File "C:\Python23\lib\xml\dom\minidom.py", line 1919,
in parse
    return expatbuilder.parse(file)
  File "C:\Python23\lib\xml\dom\expatbuilder.py", line
928, in parse
    result = builder.parseFile(file)
  File "C:\Python23\lib\xml\dom\expatbuilder.py", line
207, in parseFile
    parser.Parse(buffer, 0)
xml.parsers.expat.ExpatError: not well-formed (invalid
token): line 420, column 106

The second one (201A) produces this output:

Traceback (most recent call last):
  File "G:\_Prog\TMworks\domtree.py", line 7, in ?
    dom=parse(tm)
  File "C:\Python23\lib\xml\dom\minidom.py", line 1919,
in parse
    return expatbuilder.parse(file)
  File "C:\Python23\lib\xml\dom\expatbuilder.py", line
928, in parse
    result = builder.parseFile(file)
  File "C:\Python23\lib\xml\dom\expatbuilder.py", line
207, in parseFile
    parser.Parse(buffer, 0)
xml.parsers.expat.ExpatError: mismatched tag: line 624,
column 2

Deleting these two characters in the whole document
produces the desired result.

I don't see why these characters should be of any
problem, especially the quotation mark.
