Fix bug in Example D

[Mankarse]

The example pattern '%[^ 0-9A-z]%' did not match characters in the range 91-96, even though they are not numbers, letters, or spaces.
For example:
SELECT position = PATINDEX('%[^ 0-9A-z]%', 'Please^ensure the door is locked!');
returns 33, but it should return 7.
With the proposed update, it works correctly.

@Mankarse What collation are you using. I am using SQL_Latin1_General_CP1_CI_AS. and the code works as expected.

[Mankarse]

I have tried a variety of different collations. It is true that the original code works correctly in SQL_Latin1_General_CP1_CI_AS, but the only version that works correctly in every Latin collation that I tried is the version that I suggested.

SELECT
    [[^ 0-9A-z]] SQL_Latin1_General_CP1_CI_AS] = PATINDEX('%[^ 0-9A-z]%' COLLATE SQL_Latin1_General_CP1_CI_AS, 'Please^ensure the door is locked!') --7
   ,[[^ 0-9A-z]] SQL_Latin1_General_CP1_CS_AS] = PATINDEX('%[^ 0-9A-z]%' COLLATE SQL_Latin1_General_CP1_CS_AS, 'Please^ensure the door is locked!') --7
   ,[[^ 0-9A-z]] Latin1_General_CI_AS]         = PATINDEX('%[^ 0-9A-z]%' COLLATE Latin1_General_CI_AS        , 'Please^ensure the door is locked!') --7
   ,[[^ 0-9A-z]] Latin1_General_CS_AS]         = PATINDEX('%[^ 0-9A-z]%' COLLATE Latin1_General_CS_AS        , 'Please^ensure the door is locked!') --4
