Henri Yandell commented on LANG-1142:
-------------------------------------
It definitely should use toTitleCase. I wonder when that changed. :(
Looks like it was changed in
http://svn.apache.org/viewvc/commons/proper/lang/trunk/src/main/java/org/apache/commons/lang3/StringUtils.java?r1=1673944&r2=1673943&pathrev=1673944
- https://issues.apache.org/jira/browse/LANG-1058 - which fortunately is
unreleased.
> 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
> Components: lang.*
> 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?
