             Summary: StringUtils#capitalize: Javadoc says toTitleCase; code uses toUpperCase
                 Key: LANG-1142
                 URL: https://issues.apache.org/jira/browse/LANG-1142
             Project: Commons Lang
          Issue Type: Bug
    Affects Versions: 3.4
            Reporter: Sebb


The capitalize Javadoc says the code uses  Character#toTitleCase, however the code actually uses Character#toUpperCase.

Generally these produce the same result, but some charsets may have different characters for upper and title case - see for example the Javadoc [1] for Character#isTitleCase.

The way I read this, the character that looks like "lj" is lower-case, "LJ" is upper case and "Lj" is title case - i.e. not the same.

The question here is: should the code be corrected to use TitleCase or should the Javadoc be corrected to use UpperCase?
