The existing tests assert on filter results, which stay correct for ASCII values even when the collation is never applied. Add a test which asserts on the lookup's own compiled output, so that the mechanism failing open is caught rather than passing silently. Explain why the placeholder is compared literally: a field declaring its own get_placeholder() compiles to something other than '%s', and splicing a COLLATE clause into that is not safe, so any other right-hand side is left alone. The documentation note described the folding as specific to the German eszett. It is the common example rather than the rule: the collation treats a character as equivalent to the sequence it expands to in upper case, which also covers ligatures. Note too that a case-insensitive exact match on a collated field may now return more than one object. |
