NAME_MAX is 255. On Windows this is the number of UTF-16 chars unfortunately. On POSIX systems (as on Cygwin) this is the number of bytes. Long UTF-16 strings in cyrillic take twice as much UTF-8 chars as it has UTF-16 chars, so NAME_MAX in utf-8 cyrillics translates into a maximum of 127 UTF-16 chars. If you need access to UTF-16 filenames with more characters, you can switch to a one-byte charset temporarily, e.g. $ LC_ALL=3Dru_RU your_app to switch to iso-8859-5 or $ LC_ALL=3Dru_RU.CP1251 to switch to Windows codepage 1251.
