OGR has no direct support for filter encoding. It can just accepts SQL requests
and blindly forwards it to sqlite/postgres/mysql/oracle/filegdb/ingres etc...
Filter Encoding -> SQL conversion must be done in TinyOWS code.

As far as the capabilities of OGR SQL own engine, they are described here :
http://gdal.org/ogr/ogr_sql.html . But I doubt this is really interesting for
TinyOWS goal, unless you want to support editing shapefiles through WFS/T ;-)
