[EP-tech] Error when running irstats



Hi Agung,
I think this might be a problem with how MySQL handles UTF-8 data.

What MySQL refers to as UTF-8 cannot handle 4-byte UTF-8 characters.
Yes - this is very stupid

This explains it well: https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fmathiasbynens.be%2Fnotes%2Fmysql-utf8mb4&data=01%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7C3d6bf4f680ee4fb834d408d69292c893%7C4a5378f929f44d3ebe89669d03ada9d8%7C1&sdata=0Fe4vZYE86uDtRmBOifeCwDYg%2FDM6jkWk%2FWs0PBzMcA%3D&reserved=0, and has some solutions.

This might also be useful:

Does that help at all?

Cheers,
John
