============

unicode_mayo

============

**unicode_mayo** is the mayo in your unicode sandwich. In your development

environment, use it as a wrapper around unicode and byte strings to see if

they're accidentally coming in to contact with byte strings. This can help

catch unicode encode/decode errors before they happen in production!

**unicode_mayo** includes two classes: ``UnicodeSafetyWrapper`` and

``BytestringSafetyWrapper``. The former is meant to envelope unicode strings,

and warns when they come into contact with byte strings; the latter is meant

for byte strings, and warns when it comes into contact with unicode. Place

these in strategic places (likely in development environments only), like

``gettext()`` or all strings from your database.

Installation

============

Installation via ``pip``::

    pip install unicode_mayo

Usage

=====

Something like::

    >>> import unicode_mayo

    >>> wrapped = unicode_mayo.UnicodeSafetyWrapper(u'safety at last!')

    >>> wrapped.encode('utf-8')

    'safety at last!'

    >>> wrapped + u' woohoo!'

    u'safety at last! woohoo!'

    >>> wrapped + 'evil bytestring'
