/**
*
* The omnifaces.ToUpperCaseConverter is intented to convert submitted {@link String} values to upper case
* based on current {@link Locale}. Additionally, it trims any whitespace from the submitted value. This is useful for
* among others zip code inputs.
*
* This converter does by design no conversion in getAsString().
*
*
Usage
*
* This converter is available by converter ID omnifaces.ToUpperCaseConverter. Just specify it in the
* converter attribute of the component referring the String property. For example:
*
* <h:inputText value="#{bean.zipCode}" converter="omnifaces.ToUpperCaseConverter" />
