Re: mysql-connector-cpp-8.0.20 CDK Error: Failed string conversion

Hi Luis,

I checked my code on debug and release.
I have table with strings(about 100000 rows). And only one symbol make throwing the exeption.

Platform: win10 vs2019 toolkit v141.

Here is some more information:

auto res = session.sql(u8"SELECT '\uff08'").execute(); // this string read with exeption
//auto res = session.sql(u8"SELECT '（'").execute(); // behavior is the same like \uff08
//auto res = session.sql(u8"SELECT '\u0041'").execute(); // normal execution without exception. print "A" to output.
try {
auto & column = res.getColumn(0);
std::cout << column.getType() << std::endl; // output "STRING"
std::cout << column.getCharacterSetName() << std::endl; // output "utf8mb4";
auto row = res.fetchOne().get(0); // throw exception here
std::cout << row << std::endl;
}
catch (std::exception ex) {
std::cout << ex.what() << std::endl; // output: "CDK Error: Failed string conversion";
}
