The mayo on your unicode sandwich

Project description

unicode_mayo is the mayo in your unicode sandwich. In your development environment, use it as a wrapper around unicode 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!

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'
