"""WSGI Request API Object
This object represents a WSGI request with a more friendly interface.
This does not expose every detail of the WSGI environment, and attempts
to express nothing beyond what is available in the environment
dictionary.
The only state maintained in this object is the desired ``charset``,
its associated ``errors`` handler, and the ``decode_param_names``
option.
The incoming parameter values will be automatically coerced to unicode
objects of the ``charset`` encoding when ``charset`` is set. The
incoming parameter names are not decoded to unicode unless the
``decode_param_names`` option is enabled.
When unicode is expected, ``charset`` will overridden by the the
value of the ``Content-Type`` header's charset parameter if one was
specified by the client.
The class variable ``defaults`` specifies default values for
``charset``, ``errors``, and ``langauge``. These can be overridden for the
current request via the registry.
The ``language`` default value is considered the fallback during i18n
translations to ensure in odd cases that mixed languages don't occur should
the ``language`` file contain the string but not another language in the
accepted languages list. The ``language`` value only applies when getting
a list of accepted languages from the HTTP Accept header.
This behavior is duplicated from Aquarium, and may seem strange but is
very useful. Normally, everything in the code is in "en-us". However,
the "en-us" translation catalog is usually empty. If the user requests
``["en-us", "zh-cn"]`` and a translation isn't found for a string in
"en-us", you don't want gettext to fallback to "zh-cn". You want it to
just use the string itself. Hence, if a string isn't found in the
``language`` catalog, the string in the source code will be used.
*All* other state is kept in the environment dictionary; this is
essential for interoperability.
You are free to subclass this object.
