It's not that complicated, but I think most fonts don't support arbitrary combinations with combining enclosing circle because there is little or no demand for them. BabelStone Han displays Japanese Hiragana Letter Yu + Combining Enclosing Circle quite well, but on the other hand it does not work so well with CJK ideographs, and fails with Latin letters and punctuation. > 4.In CJK Symbols and Punctuation, Proper name mark and Book name mark are > not included.

I agree. However, if you really do want to represent underlining of proper names at the character encoding level, then you would have to do something like put U+0332 Combining Low Line after each character to be underlined, and select a font that supports Combining Low Line with CJK ideographs. BabelStone Han supports this low-level method of underlining CJK ideographs, but if you want a space in the underlining between 美國 and 紐約 you would have to insert a very thin space (U+200A Hair Space in this example) between the characters.
