#1609: WXGUI doesn't offer a supported encodings for "Attribute data encoding"
setting
-------------------------+--------------------------------------------------
Reporter: marisn | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 6.4.3
Component: wxGUI | Version: 6.4.2
Keywords: | Platform: Unspecified
Cpu: Unspecified |
-------------------------+--------------------------------------------------
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
