 If user needs to set an encoding for attribute data, he isn't given a list
 of supported encodings. User entered encoding is not checked before use.

 Example: after setting encoding to "CP-1257" (a valid encoding for Baltic
 languages in MS-Windows), WXGUI preferences dialog accepts it, still later
 attribute query fails with:

 {{{

 }}}

 Solution:
  * WXGUI should use "system" encoding by default, if user hasn't set one
 in his preferences thus avoiding a need to change it for most of use cases
  * WXGUI should provide a drop-down list with all supported encodings to
 avoid ability to set a valid, still unsupported encoding
