Jason Dere commented on HIVE-6843:
----------------------------------
Should this also work for unicode characters which require more than one Java
character? If you add these checks to TestGenericUDFUtils, the 2nd check fails:
{code}
Assert.assertEquals(3, GenericUDFUtils.findText(new
Text("123\uD801\uDC00456"), new Text("\uD801\uDC00"), 0));
Assert.assertEquals(4, GenericUDFUtils.findText(new
Text("123\uD801\uDC00456"), new Text("4"), 0));
{code}
This would require using String.codePointCount() on the indexOf() result.
> INSTR for UTF-8 returns incorrect position
