Walkthrough

A UTF-8 validation step was introduced at the beginning of the Cursor::executescript method in the SQLite module. The method now ensures that the script string is valid UTF-8 before proceeding with further processing or database operations. No public API signatures were changed.

Poem

The bunny checks your script with care,
Ensuring UTF-8 is always there.
Before the database gets a peek,
No sneaky bytes can make it weak!
With every hop, the code grows tight—
Bugs and errors hop out of sight.

1643-1643: Excellent placement of UTF-8 validation.

This change correctly implements the PR objective to raise UnicodeEncodeError for surrogates in sqlite.executescript. The validation is placed optimally before any database operations, locks, or resource allocation, following the "fail fast" principle.
