Thanks for pointing me SysExporter, Alan_B! Seems it is usefull utility.
But it doesn't help in my case because it exports into 8-bit encoding text files too (as Recuva itself).
I have tried SysExporter 32-bit under win7x32 and SysExporter 64bit under win7x64.
SysExporter saves file using ISO-8859-1 encoding: it replaces cyrillic symbols to '?':'
E:\Files\Espa<F1>a\Barcelona\????\
(example is for the same file as on my picture from my first post).
