[jira] [Created] (LANG-1017) Use non-ASCII digits in Javadoc examples for StringUtils.isNumeric

Christoph Schneegans created LANG-1017:
------------------------------------------

             Summary: 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
            Priority: Trivial


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
