(foo-[\xMM-\xNN])
Classification: Mono
Product: Mono: Class Libraries

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:
False
Expected Results:
True
