EPC QR code — 312 characters but 338 bytes: over the 331-byte cap
The trap the spec spells out and implementations still fall into: EPC069-12 caps the payload at 331 BYTES, not characters. This Polish payload is 312 characters — comfortably under any character count — but the accented letters cost two bytes each in UTF-8, so it weighs 338 bytes and is rejected.

Every file in this library is run through the site's own validator on each build. The expected result stated above is asserted by an automated test — if a file stopped matching what this page claims, the build would fail. Two inherited fixtures were repaired this way before publication: three IBANs failed the mod-97 check and several names used characters outside the basic SEPA character set.
