'à' french character display using JSON shows error

Question

I have a french character (à) in my JSON String 'd'instruments cordes à'. But the (à) character shows JSON error when displaying. I want to display the exact character in my UI.

You really should provide more details. As of now, it's unclear whether you are generating or parsing your JSON in the database.

Regardless, below is a short sample demonstrating that "à" is not a special character in any way. Compare the code below with yours, and especially pay attention to the difference between varchar and nvarchar. I think that's where your problem is.

declare @j nvarchar(max);

declare @t table (
    Id int,
    Value nvarchar(100),
    Country varchar(50)
);

insert into @t (Id, Value, Country)
values
    (634149, N'd''instruments cordes à', 'America');

-- Shows data in the table
select * from @t;

set @j = (
    select *
    from @t t
    for json path, without_array_wrapper
);

-- Shows generated JSON
select @j as [GeneratedJSON];

-- Shows JSON query output
select *
from openjson(@j) with (
    Id int '$.Id',
    Value nvarchar(100) '$.Value',
    Country varchar(50) '$.Country'
) j;
