UnderscoreToCamelCase fails with digits

[vmasciotta]

$string = 'ABC_0001'; 
$filter = new \Zend\Filter\Word\UnderscoreToCamelCase(); 
echo $filter->filter($string); //returns ABC_0001 

If $string = 'ABC_Z0001';, so You add a character after the underscore then You get ABCZ0001.

Now, it's fine for me that I get everything in uppercase, but the underscore shouldn't be there anymore. Am I wrong?

There is a similar issue with SeparatorToCamelCase that was fixed in the develop branch here - #6156

@vmasciotta @Ocramius I think it can be closed as already fixed in develop as @moderndeveloperllc said

@moderndeveloperllc @samsonasik thanks, closing!
