Char < operator not working

[fanoI]

Trying to do this code on a char when the value interpreted as number (the codepoint) is > SHORT_MAX this tests fails:

       private byte GetByte(char ch)
        {
            /* ch is in reality an ASCII character? */
            //if (ch >= 0 && ch < 127)
            if (ch < 127)
            {
                //mDebugger.SendInternal($"ch {(ushort)ch} is ASCII");
                return (byte)ch;
            }

	   return 42;
}

For the same cause Char.IsSurrugate(ch) returns false.

This the IL that this code generates:

GetByte:
IL_0000:  nop         
IL_0001:  ldarg.1     
IL_0002:  ldc.i4.s    7F
IL_0004:  clt         
IL_0006:  stloc.0     
IL_0007:  ldloc.0     
IL_0008:  brfalse.s   IL_0010
IL_000A:  nop         
IL_000B:  ldarg.1     
IL_000C:  conv.u1     
IL_000D:  stloc.1     
IL_000E:  br.s        IL_0015
IL_0010:  ldc.i4.s    2A 
IL_0012:  stloc.1     
IL_0013:  br.s        IL_0015
IL_0015:  ldloc.1     
IL_0016:  ret
