Description

STEPS TO REPRODUCE:

StringUtils.replaceIgnoreCase("\u0130x", "x", "")

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.
