It is possible. We can use unix representation to obfuscate control words.
For example {*\o\'62jdata is the same {*\objdata
Instead letter b we put the same but in unix representation \'62
Here 62 - is HEX value of char b.
Question
I wonder is it possible to obfuscate control words in RTF standard? For example instead \objemb it will be something like \%6F%62%6A%65%6D%62

The RTF Specification suggests that this is not possible:
A control word is defined by: \<ASCII Letter Sequence><Delimiter> where <Delimiter> marks the end of the control word’s name
It then goes on to say:
The <ASCII Letter Sequence> is made up of ASCII alphabetical characters (a through z and A through Z).
The reference parser implementation at the end of the specification follows this definition, and doesn't have any scope for dealing with escaped characters.
