reduce `single_char_pattern` to only lint on ascii chars This should mostly fix the `single_char_pattern` lint, because with a single byte, the optimizer will usually see through the char-to-string-expansion and single loop iteration. This fixes #11675 and #8111. Update: As per the meeting on November 28th, 2023, we voted to also downgrade the lint to pedantic. --- changelog: downgrade [`single_char_pattern`] to `pedantic`
