---------------------------------------
Fixed in revision 1599322. I've also added test cases for the new example.
Thanks for the pointer!
> Use non-ASCII digits in Javadoc examples for StringUtils.isNumeric
> ------------------------------------------------------------------
>
> Key: LANG-1017
> URL: https://issues.apache.org/jira/browse/LANG-1017
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Affects Versions: 3.3.2
> Reporter: Christoph Schneegans
> Assignee: Benedikt Ritter
> Priority: Trivial
> Fix For: 3.4
>
>
> The Javadoc comment for the method
> org.apache.commons.lang3.StringUtils.isNumeric(CharSequence) contains a
> single "true" case, namely
> \* StringUtils.isNumeric("123") = true
> Hence, one might wrongly assume that this method is suitable to check whether
> a string consists only of ASCII digits (U+0030..U+0039).
> Consider providing another "true" case, e.g. using Devanagari digits:
> \* StringUtils.isNumeric("१२३") = true
> \* StringUtils.isNumeric("&\#x967;&\#x968;&\#x969;") = true
