[jira] [Commented] (LANG-1453) StringUtils.removeIgnoreCase("İa", "a") throws IndexOutOfBoundsException
[ https://issues.apache.org/jira/browse/LANG-1453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16923235#comment-16923235 ]
Chen commented on LANG-1453:
----------------------------
Since case mappings are not always 1:1 char mappings, the resulting may be a different length than the original， so String#toUpperCase & String#toLowerCase can't be used with String#indexOf which to find position.
How to fix this problem? I think we should use regex. I will try it later.
