WordDelimiterFilter and acronyms normalization

Hi all!

Is there any ready-for-use filter which performs acronyms normalization such
as "I.N.C."->"INC"?

I see that Lucene's StandardFilter can do this but we can't use it as we're
using WhitespaceTokenizer instead of StandardTokenizer.

I am bad at regular expressions but if you can write a regex for that replacement solr.PatternReplaceFilterFactory can do that.

<filter class="solr.PatternReplaceFilterFactory" pattern="([^a-z])" replacement="" replace="all" />
