Newbie: plist & control characters?

I'm trying to modify a plist file. The modification works properly,
but I'm having difficulties in finding the proper way to restore.

The file contains HTML strings like "$#226;" and either this gets
replaced by "â" (which I don't want) but the programme completes or
the program fails when I try to use the data wrapper.

I must be doing something wrong, but can't find what (and this
includes Google searches). Please help.

Failing text:
def omkattenAgents(AANGRIJPINGSPUNT, KLANTNAAM_OUT, KLANTNAAM_IN,
ZOEKSET1_OUT, ZOEKSET1_IN, ZOEKSET2_OUT, ZOEKSET2_IN):
	<other programme text>

		tussentekst =
plistlib.Data(plistlib.readPlist(os.path.join(root,bestandsnaam)))
		tussenblok = tussentekst.data
		ding = tussenblok['RepresentedObject']
		tekststring = ding.get('Name')

		tekststring_0 = tekststring.replace(KLANTNAAM_OUT,KLANTNAAM_IN)
		tekststring_1 = tekststring_0.replace(ZOEKSET1_OUT,ZOEKSET1_IN)
		tekststring_2 = tekststring_1.replace(ZOEKSET2_OUT,ZOEKSET2_IN)
		tekststring_3 =
tekststring_2.replace(ZOEKSET1_OUT_LOWER,ZOEKSET1_IN_LOWER)
		tekststring_4 =
tekststring_3.replace(ZOEKSET2_OUT_LOWER,ZOEKSET2_IN_LOWER)

		ding['Name'] = tekststring_4
		tussenblok['RepresentedObject'] = ding
		tussentekst.data = tussenblok

		plistlib.Data(plistlib.writePlist(tussentekst,
os.path.join(root,bestandsnaam)))

    self.writeData(value)

    for line in data.asBase64(maxlinelength).split("\n"):
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/
python2.6/plistlib.py", line 379, in asBase64
    return _encodeBase64(self.data, maxlinelength)
  File "/Library/Frameworks/Python.framework/Versions/2.6/lib/
python2.6/plistlib.py", line 361, in _encodeBase64
    chunk = s[i : i + maxbinsize]
TypeError: unhashable type


The difference between failure and completion with replacing HTML is
the statement
tussentekst.data = tussenblok (failure)
tussentekst = tussenblok (completion with replacing)
