 I've found a case where unum_parseDoubleCurrency is not doing what I
expect.  The value I pass in is $1234567890q123460000.00 and this
returns with a status of zero error & a parse pos of 22 (I would
expect a parse error at position 11).

I stepped into DecimalFormat::subparse() and it looks like it parses
the first 10 digits and then stops parsing at the q but doesn't set an
error. Then later in DecimalFormat::parse() the value gets crammed
into a long (which greatly truncates the value).

This is very problematic for me 'cause I try to remove chars that are
invalid but this allows my users to enter bad chars and truncates
their data!
