escape() decodes UTF-8 byte sequences before HTML-escaping them, and str.join() escapes raw strings when concatenating with Markup elements.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

escape() converts bytes objects via str() to their literal repr 'b\'...\'' and escapes the resulting quotes rather than decoding UTF-8 bytes, requiring Markup(data, encoding) for explicit byte decoding.
Markup.format_map() queries Mapping instances dynamically without requiring keyword unpacking, auto-escaping plain string values while preserving Markup instances.
Markup subclasses preserve their custom subtype across escape classmethods, binary additions, partitions, splits, and case transformations.
Markup.__radd__ auto-escapes left-hand plain string operands during concatenation, whereas str.join returns an unescaped plain str.
Markup.replace matches search targets literally against the internal escaped representation and auto-escapes plain string replacement arguments.
