Why can't it find the entry in the database?

Question

SQL

Hello!
When querying the database, it does not find a record. There is a record in the database. The problem, I think, is in the characters that the search string contains.
Database query:

.....
var stringValueName = c.Name.Replace("\"", "");
db.Table.FirstOrDefault(s=> s.Name.Replace("\"", "").Contains(stringValueName));
.....

The stringValueName variable has the following value: Capacitor K53-68-25V-10uF+-20%"C"
There are quotes in the variable, I think that's the problem. But I don't know how to correct this error. Please help.

Latin-Cyrillic can't play dirty tricks?
And then in the above example, at least 3 letters have a 1: 1 style (K, B, C)
