The Shapefile Reader / DBF file reader should be able to detect code-point files (CPG file extension) and adjust reading to handle non-ASCII cases.

Currently, the reader expect String inputs to be either ASCII or ISO-8859-1 (it doesn't distinguish between them). It should probably be able to handle at least UTF-8 and maybe in ISO-8859-1 mode make sure that it screens out non-valid charac
