Hi Jordan,

Thank you very much for the comments.

You should also include at least one test to show that the fix-it still lines up properly with the replacement range.

I was thinking about that too, but I couldn't find any test case that
would produce multiple fix-it hints on the same line and allow me to
use arbitrary Unicode string before the last hint. I tested it
internally by hard-coding
"Hints.push_back(FixItHint::CreateInsertion(Location, UnicodeString))"
into the code.

Even if we are able to do that, I am also not sure how can check the
location of printed fix-its because different systems will render
Unicode characters differently, as commented in
test/FixIt/fixit-unicode.c.

Do you have any recommendations on how I should go about this?

Thank you,
Sukolsak
