In reply to Girish.

The curly bracket has a special meaning to RTF. It designates the start of a command, which should not be printed. However, that does not mean you cannot display them as plain text. You can use the PROTECTSPECIALCHARS style attribute on the column that contains the curly bracket to tell RTF to view them as plain text. You should then see them as part of the value in your final file.
data a;
length value $20;
input value $;
cards;
abcd
adga{
}dsflj
{sdlfj}
;
ods rtf file='test.rtf';
proc report data=a;
define value / style( column) = { protectspecialchars = on};
run;
ods rtf close;
