David,
PatternReplaceCharFilterFactory accepts pattern and replacement args.
Please read PatternReplaceCharFilter javadoc to see few samples:

Does anyone out there know how to use PatternReplaceCharFilterFactory?
The closest think to an example I see is in the default schema.xml:
<!--
The PatternReplaceFilter gives you the flexibility to use
Java Regular expression to replace any sequence of
characters
matching a pattern with an arbitrary replacement string,
which may include back references to portions of the
original
string matched by the pattern.
See the Java Regular Expression documentation for more
information on pattern and replacement string syntax.

html
-->
<filter class="solr.PatternReplaceFilterFactory" pattern="([^a-z])"
replacement="" replace="all"/>
I'm not sure how the PatternReplaceCharFilterFactory differs from the
PatternReplaceFilterFactory. Can anyone give me an example of how to
strip all commas for example using this technique?
Thanks!
