Solve the problem of pinyin ambiguity

As an example, enter 吧巴八 in "Characters" field. Note that in review phase, you will be asked to write "bā“ twice even though the application means two different characters. A simple improvement would IMHO be to add radical in those cases - we already have it in dictionary.txt, so it's a matter of detecting this case and adding it.

I pushed the solution, but it appears it's only partial, which is why I decided to remove "good first issue" tag - apparently it's not trivial.
