These views reference strings in parts of URLs or other components that are percent-encoded. The special characters (those not in the allowed character set) are stored as three character escapes that consist of a percent sign ('%%') followed by a two-digit hexadecimal number of the corresponding unescaped character code, which may be part of a UTF-8 code point depending on the context.
The view refers to the original character buffer and only decodes escaped sequences when needed. In particular these operations perform percent-decoding automatically without the need to allocate memory:
These objects can only be constructed from strings that have a valid percent-encoding, otherwise construction fails. The caller is responsible for ensuring that the lifetime of the character buffer from which the view is constructed extends unmodified until the view is no longer accessed.
