Table1 has nvarchar column called umsg which contains unicode text and some time english also.

I want to find out English text present in umsg column.

select * 
from table1 
where 
    RDate >='01/01/2014' and RDate < '09/26/2017' 
    and umsg = convert(varchar(max), umsg)

I used above query that work fine in regional language but some time fail. Suppose col contain text like 'ref no Ã©tÃ©' I think above message is unicode, if I used above query, it/sql is showing me as English not unicode.How to handle this.

What I have tried:

select * 
from table1 
where 
    RDate >='01/01/2014' and RDate < '09/26/2017' 
    and umsg = convert(varchar(max), umsg)
