Importing a file containing custom data validation and the "@" symbol throws a js error

Bug report

When importing a xlsx file containing custom data validation and the "@" symbol a JavaScript error is thrown.

Reproduction of the problem

Import the this sample file that contains the custom validation formula =ISNUMBER(MATCH("*@*",A1,0)) in the Server Import/Export Demo. The following error is thrown and logged on the developer's console: Can't handle character with code: 64 (input: \"ISNUMBER(MATCH(\"*@*\",A1,0))\")"

Opening the file with the built-in open command works as expected as well as hardcoding the formula - REPL

Expected/desired behavior

Importing a xlsx file containing custom data validation and the "@" symbol should not throw a JavaScript error.

Environment

• Kendo UI version: 2021.3.1109
• Browser: [all]
