Granted this is not a problem for most users. It has to do with selecting text from books in Japanese. They will sometimes contain what is called ruby or furigana small "super scripts" in order to aid the reader with unusual character, especially convenient when it comes to names. For someone doing research using Japanese books these names is something you often want to highlight so you can find them again, or perhaps add a note with some relevant data. However, Marvin won't allow the "text holders" (blue bars with a dot at the end) to scroll past characters with added furigana. Hence, I can't highlight the whole word and highlighting only one character might make me miss it when I later look for it.
I wanted to add a screenshot in the hope that it makes the problem clearer. Unfortunately I can't figure out how to do that from an iPad. There is no paste command available under Safari.

Being on the subject of highlights a real beneficial tool would be the ability to search for highlights by color. For example I might highlight places in pink, then being able to accumulate those in one color search would be productivity enhancing.
