Comment (by siliconforks):

 The comments for the `IdnaEncoder::to_ascii()` method and the
 `IdnaEncoder::MAX_LENGTH` constant are not very clear, but I don't think
 the intention is that an entire URL can be passed to the `to_ascii()`
 method.  It's just for domain names.  But I don't even think it's allowed
 to pass an entire domain name to the `to_ascii()` method.  You have to
 break the domain name up into its component parts (these are usually
 called "labels" in standards documents) and those are what can be passed
 to `to_ascii()`.

 I think you can pass an entire domain name (but not an entire URL) to the
 `IdnaEncoder::encode()` method.
