@kinow May be try to store a original text.length before performance any
upper || lower case operation and make use of it?

> URL: https://issues.apache.org/jira/browse/LANG-1406
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.*
> Reporter: Michael Ryan
> Priority: Major
>
> 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.
