[jira] Commented: (CODEC-57) Metaphone.metaphone(String) returns an empty string when passed the word "why".

["Henri Yandell (JIRA)" <ji...@apache.org>]

Henri Yandell commented on CODEC-57:
------------------------------------

I think that unless we hear otherwise, we should not change the CC/GG bit. People's data needs to be likely to work, regardless of the better algorithm etc.

With this specific bug though, having an empty string feels bad. Both the Ruby and Python implementations do WH->W. I don't feel a huge urge to make it WH->H just to match PHP. I'm more tempted to do the WY->Y. 

Any thoughts?

> An empty string is returned from the Metaphone.metaphone(String) method when passed the value "why". Variations on the value, such as "wwwhy" and "wwhhhy" also return empty strings.
> This appears to be an issue since other implementations of the metaphone algorithm, namely the PHP version, returns "H" when passed the value "why".
