    Just leaving a comment here too to have a review here in GitHub. While your example works,
as the character is considered already in upper case, the reverse case would still fail after
changing from `toLowerCase` to `toUpperCase`. So I think we should find another solution or
update the documentation stating how the code works with unicode.

> STEPS TO REPRODUCE:
> {code}
> StringUtils.replaceIgnoreCase("\u0130x", "x", "")
> {code}
> EXPECTED: "\u0130" is returned.
> ACTUAL: StringIndexOutOfBoundsException
> This happens because the replace method is assuming that text.length() == text.toLowerCase().length(),
which is not true for certain characters.
