Question - are your results that are inside of rigLs truly the direct
result of a call to cmds.listRelatives()? Are you sure that the objects
inside of rigLs are truly strings (or unicode)?
I ask because I've noticed that in maya 2015, a repr was added to
MObjects... which would be nice, except that the definition really would
have been more appropriate for __str__, not __repr__, as it can make it
hard to tell that you are working with MObjects, and not just strings.
To see what I mean, try running this in Maya 2015*:
import maya.cmds as cmds
# set up the indicated hierarchy
cmds.createNode('transform', name='male01')
cmds.group(name='characterRig')
cmds.group(name='SceneGrp')
# and set up rigLs / charLs as indicated
rigLs = [u'male01', u'female01', u'elderly01']
parent = '|SceneGrp|characterRig'
charLs = cmds.listRelatives(parent, c=True)print charLs# [u'male01']
# this works as expected...
diff1 = list(set(charLs)-set(rigLs))print diff1# []
diff2 = list(set(rigLs)-set(charLs))print diff2# [u'female01', u'elderly01']
# but if you were to somehow end up with MObjects, the results may
seem confusing
def apiGetChildren(parent):
# you can ignore the inner workings of this, just know that it will act like
# cmds.listRelatives(parent, c=True), except return api MObjects
import maya.OpenMaya as om
sel = om.MSelectionList()
sel.add(parent)
parentObj = om.MObject()
sel.getDependNode(0, parentObj)
parentMFn = om.MFnDagNode(parentObj)
return [parentMFn.child(i) for i in xrange(parentMFn.childCount())]
charLs = apiGetChildren(parent)
# in maya2015, charLs now SEEMS to be the same as before...print
charLs# [u'male01']
# ...but you'll get unexpected results...
diff1 = list(set(charLs)-set(rigLs))print diff1# [u'male01']
diff2 = list(set(rigLs)-set(charLs))print diff2# [u'male01',
u'female01', u'elderly01']
If you think something like this is going on, you can do this:
print charLsprint [type(x) for x in charLs]print rigLsprint [type(x)
for x in rigLs]
...and let us know what you get.

*Note, I wasn't actually able to test this in Maya 2015, but it should act
like this from what I recall. Not 100% sure that the MObject.__repr__
returns unicode, as opposed to just str, though...
