…nitfunc() The builtin loader info encoded the module name as ASCII, so a non-ASCII spec name failed with UnicodeEncodeError even for multi-phase init modules, which support such names when loaded dynamically. Fall back to UTF-8 and mark the name as non-ASCII, so that multi-phase init works and single-phase init is rejected with the same error as for dynamically loaded extensions.
