Do "ú" and "usa" mean the same thing in a sentence?

In ordinary Portuguese text, does "ú" or "usa" show up more?

"usa" is the more common of the two: it sits at frequency rank #1,103 in our Portuguese list, against #44,175 for "ú". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
