the function strtoUCS() is used to convert local pathname/filename characters
to UCS unicode (2 bytes/char), to be used on the wire against a server
which is supporting that char encoding.
The kernel function char2uni() is used to convert each local char to UCS
unicode. In case of error, it returns -EINVAL (== -22).
Note:
  In that error case, the failing character is replaced by an
  UCS question mark "?" (0x003f)! 

 - what kind of local character encoding (utf-8, ...) are you using?
 - have you used the mount option "iocharset=..." to overwrite that encoding?
 - what pathnames/filenames are used when that log msg is written?
