Only if such translation is made right. Remember charset introducers.

They're a problem, but it may only cause a cache miss, not a false match, right?

But apparently to transform the query before using it as a cache key is a right idea. Two queries different only by some whitespaces, comments or case (unless in literals) should not miss the cache.

In the ideal world, maybe. But this is *much* more complicated than it seems at the first glance.
