There's a lot to unpack here, but the tl;dr is to refer to the charset ultimately to determine if the data is UTF8, if it is, we can decode it to a UTF8 string. This fixes behavior around CHAR/TEXT fields with a binary collation, being surfaces as BINARY/BLOB types by MySQL. For all intents and purposes, BLOB/BINARY/CHAR/TEXT are all effectively identical and interchangeable, the only differentiator is their charset. Either they are a UTF-8 charset, or a binary charset or some other charset. Fixes #169

There was a problem hiding this comment.
This helper was nice becuase it makes it easier to copy/paste the hex output from mysql CLI for it's rendering of binary data. Figured I'd like to have a source of truth to copy/paste from rather than hand writing each byte in a Uint8Array.

There's a lot to unpack here, but the tl;dr is to refer to the charset ultimately to determine if the data is binary, or non-binary which is always UTF-8.
This fixes behavior around CHAR/TEXT fields with a binary collation, being surfaces as BINARY/BLOB types by MySQL.
For all intents and purposes, BLOB/BINARY/CHAR/TEXT are all effectively identical and interchangeable, the only differentiator is their charset. Either they are a binary charset, or they are encoded as UTF-8.
This behavior seems to differ slightly from vanilla MySQL and is specific to potentially a bug in Vitess, but this default is much safer for future proofing if we fix things there.
Fixes #169 #171
