Find non-ASCII characters in varchar columns using SQL Server

How can rows with non-ASCII characters be returned using SQL Server?
If you can show how to do it for one column would be great.

I am doing something like this now, but it is not working

select *
from Staging.APARMRE1 as ar
where ar.Line like '%[^!-~ ]%'

For extra credit, if it can span all varchar columns in a table, that would be outstanding! In this solution, it would be nice to return three columns:

• The identity field for that record. (This will allow the whole record to be reviewed with another query.)
• The column name
• The text with the invalid character

 Id | FieldName | InvalidText       |
----+-----------+-------------------+
 25 | LastName  | Solís             |
 56 | FirstName | François          |
100 | Address1  | 123 Ümlaut street |

Invalid characters would be any outside the range of SPACE (32₁₀) through ~ (127₁₀)
