figures.. Solaris 5.10 isn't close to POSIX...
grep -q is the 'silent' way to look for a pattern it suppreses the display, but returns a status value ($?) to indicate whether it succeeded or not. See if one of your options does that.

( stuff in here )Tj is the way a postscript ()show command is written to uncompressed pdf format files. This displays "stuff in here".

'(X)Tj$' is the pattern for the command to print a single character 'X'. Again in uncompressed format.

If you literally cannot read your pdf because it is full of really weird characters, then it is compressed and this method will not work.
