Description of problem:

THe RHEL6 cluster itself is able to handle unicode characters in names and parameters just fine. Unicode characters like national ones are however not usable when managing the cluster from within luci - the communication part of luci is not able to handle them as seen in a traceback that appears anytime an attempt to use a unicode character is made (full log attached below):

Traceback (most recent call last):
  File "/usr/lib/python2.6/site-packages/luci/lib/ricci_communicator.py", line 328, in batch_run
    batch_xml = minidom.parseString(batch_xml_str).firstChild
  File "/usr/lib/python2.6/site-packages/_xmlplus/dom/minidom.py", line 1925, in parseString
    return expatbuilder.parseString(string)
  File "/usr/lib/python2.6/site-packages/_xmlplus/dom/expatbuilder.py", line 942, in parseString
    return builder.parseString(string)
  File "/usr/lib/python2.6/site-packages/_xmlplus/dom/expatbuilder.py", line 223, in parseString
    parser.Parse(string, True)
UnicodeEncodeError: 'ascii' codec can't encode characters in position 765-766: ordinal not in range(128)


Version-Release number of selected component (if applicable):
luci-0.26.0-26.el6.i686


How reproducible:
Always


Steps to Reproduce:
1. Create a cluster
2. Try to add a fence device/resource/service with a name or parameter containing unicode characters

  
Actual results:
The action is reported as successful but no fence device/resource/service has been really added to the cluster configuration. Luci log contains error messages.


Expected results:
Changes are applied successfully.


Additional info:
Luci sections affected:
 - fence device name / parameters
 - failover domain name
 - resource name / parameters
 - service name (including resources name / parameters)
 - cluster configuration options
