The following Files-11 Extended QIO Processor (XQP) file system
    enhancements are offered under Extended File Specifications
    through the $QIO interface. Note that in some cases, XQP file
    format rules may differ from those that apply to other system
    services that accept file names, such as those provided by RMS.

    o  The current restrictions on the format and content of file
       names have been modified, specifically:

       -  The 39.39 file name length restriction was removed to allow
          longer file names, up to 236 8-bit characters or 117 16-bit
          characters

       -  The use of characters from the ISO Latin-1 multinational
          character set is supported in file specifications

       -  Support for the entry and storage of file and directory
          specifications in Unicode.
