└─>Windows CP1250 (Slavic/Central European Languages)
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
If you want to display filenames with native language characters
from the Microsoft FAT file system family or from JOLIET CDROMs
correctly on the screen, you need to include the appropriate
input/output character sets. Say Y here for the Windows CP-1250
character set, which works for most Latin-written Slavic and Central
European languages: Czech, German, Hungarian, Polish, Rumanian, Croatian,
Slovak, Slovene.
