The prepared statement emulation layer is handling binary content in a way that creates warnings in MySQL. When analysing the query logs, we saw that the content sent to the server is missing `0x5C` characters when the using emulated prepares. This introduces a minimal test case that reproduces the issue to aid the solution.
