Functional

• Invariant character and version helpers are unverified on a console. u_charsToUChars, u_UCharsToChars, u_versionFromString, u_versionFromUString and u_versionToString follow ICU 78.1 uinvchar.cpp and putil.cpp, unchanged since 65.1. Firmware 13.42 reports ICU 78.1 and exports none of them (#11013); the 3.20 table has all five. Version parts use the guest strtoul, truncated to eight bits; u_versionToString keeps ICU's dropped zero tens digit (105 becomes 15). A null buffer with a positive conversion length throws; ICU dereferences it. Closes when: compared with the console.
