I saw this, but this has the side affect to reduce any occourance of a
duouble 0x1515 to 0x15:
g...@current:~> printf '\25\25Hello\25\12world.\12' > blah
g...@current:~> hd blah
00000000 15 15 48 65 6c 6c 6f 15 0a 77 6f 72 6c 64 2e 0a |..Hello..world..|
00000010
g...@current:~> tr -s '\25\12' '\25' < blah | hd
00000000 15 48 65 6c 6c 6f 15 77 6f 72 6c 64 2e 15 |.Hello.world..|
Thanks anyway
