[TxMt] ascii/binary

[Chad Dombrova]

hello all,
i am working with files that contain mixed ascii and binary data.  if  
i open the file in textMate and then resave it (without editing it's  
contents), parts of the binary data are incorrectly interpreted as  
line-breaks and the data becomes corrupted.

is there a way to create an ascii/binary hybrid file-type that  
textMate understands so that i can edit the ascii without ruining the  
binary data?

sorry if this is an obvious question, i'm still a textMate newb.

thanks in advance,
chad
