The Unicode Standard provides a compatibility decomposition from U+2160 
to U+0049. When doing a search, Acrobat looks for both the verbatim 
string as well as the compatibility decomposition. This is not just 
limited to Roman numerals, Acrobat will do the same for ligatures, 
superscripts and other Unicode characters that have their compatibility 
counterparts in the standard.
