           Summary: Regex does not consider range subtraction
    Classification: Mono
           Product: Mono: Class Libraries
           Version: unspecified

In the example repro, Regex.IsMatch() shows unexpected mismatch.

In general, pattern exclusion works (such as commented line above), but when it
is specified by character range, it doesn't.

Reproducible: Always

Steps to Reproduce:
using System;
using System.Text.RegularExpressions;

public class Test
        public static void Main ()
                //string pattern = @"([\p{IsBasicLatin}-\x80])+";
                string pattern = @"([\p{IsBasicLatin}-[\x80-\xFF]])+";
                string target = "application";
                Console.WriteLine (Regex.IsMatch (target, pattern));
Actual Results:  

Expected Results:
