 Seems that any operation touching attribute database fails if path
 contains non-latin letter.
 It is a single instance of a general problem of passing file names as
 arguments between GUI and modules.
 Output in CMD window:
 {{{
 GRASS_INFO_WARNING(5668,2): Unable open database
 <C:\Users\Māris\Documents\grass
 data\nc_basic_spm_grass7\PERMANENT\sqlite\sqlite.db> by driver <sqlite>
 GRASS_INFO_END(5668,2)
 }}}

 One of outputs in wxGUI command console:
 {{{
