for some reason it is not possible to change the charset encoding afterwards import process.
Mostly I have shape files in UTF-8 or Windows-1251 charset.
So it is a bit of luck to find the right charset at import process.
Would it be so difficult to change the charset afterwards?
unfortunately it's not possible to change the encoding after import. If possible, please use SHP file with .cpg definition file.
> cpg - An optional file that can be used to specify the codepage for identifying the characterset to be used.
LocusGIS is able to read this file and set the correct encoding during import
