Question Diff command for other filetypes

Hello, I have two .odt files extensions and I tried running diff command like this
Code:
[user@user ~]$ diff A_old.odt A.odt

It just returns this output, that they are different but doesnt tell me where they are different
Code:
Binary files A_old.odt and A.odt differ

so does diff command work only if the files are .txt, or .c files, or .m files (like it should be only plain text or some programming language file)
and for other kinds of file extension, what do we do for them? is there an alternative command, to know say if two versions of a .doc/ .pdf file where they are different?

NAME
zcmp, zdiff - compare compressed files SYNOPSIS
zcmp [ cmp_options ] file1 [ file2 ] zdiff [ diff_options ] file1 [ file2 ] DESCRIPTION
Zcmp and zdiff are used to invoke the cmp or the diff program on files compressed via gzip. All options specified are passed directly to cmp or diff. If only file1 is specified, it is compared to the uncompressed contents of file1.gz. If two files are specified, their con- tents (uncompressed if necessary) are fed to cmp or diff. The input files are not modified. The exit status from cmp or diff is pre- served. SEE ALSO
cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1) BUGS
Messages from the cmp or diff programs may refer to file names such as "-" instead of to the file names specified. ZDIFF(1)
