  comment:    Old Tcl scripts running on 8.6.x+ with corresponding Tcllib for crc32
              package read the files regardless of their encoding or with the system
              encoding.  Now with Tcl 9.0.1 and corresponding Tcllib the crc32
              package do the same, but the core checks for wrong encoding on read of
              file's content.  The error message from "crc32::crc32" with used
              option "-filename" gives on some files "invalid integer" than a
              checksum.  All these files have not the same encoding as used from
              system and/or simple compatible (ASCII) text.  Maybe new options for
              encoding (and/or binary or not) are needed?  Best solution for now is
              not to use the convenient way: open file for them self, fconfigure it
              to the right encoding or binary, and finally run crc32 with this
              handle, afterwards closing file and unset used temporary variables.
              (Please set the Version for Tcl 9.0.1, I use on ActiveTcl 8.6.4.1
              crc32 1.3.2 and found it on BAWT-distribution 3.0.1, thanks.)  Best
              greetings, Thomas [TWu]
