Failing tests for varchars

[piyushchauhan2011]

I came across this library and thought of contributing to it. Cloned the repo on the system and started with tests. When I ran swift test after swift build, encountered two failing tests.

/testcodes/Perfect-MySQL/Tests/MySQL/MySQLTests.swift:330: error: -[MySQLTestSuite.MySQLTests testQueryStmt2] : XCTAssertTrue failed - 1366 Incorrect string value: '\xF0\x9F\x91\xBB' for column 'varchar' at row 1 - 1366 Incorrect string value: '\xF0\x9F\x91\xBB' for column 'varchar' at row 1
