Wow!  I've never seen that regex syntax and my ancient O'Reilly (7/1997)
"Mastering Regular Expressions" book does not cover it.  Therein,
{min:max} is the "interval" quantifier, and no mention of "\p".
I tried the suggested regex in QuickSearch; but no hits.  The messages
I'm trying to filter are mostly in Chinese & Japanese; are these covered
by the above suggestion?

Thanks,
Pierre
