Depending on what's in the data, this generates one or more
``SpaceCharacters`` and ``Characters`` tokens.
For example:
>>> from html5lib.treewalkers.base import TreeWalker
>>> # Give it an empty tree just so it instantiates
>>> walker = TreeWalker([])
>>> list(walker.text(''))
[]
>>> list(walker.text(' '))
[{u'data': ' ', u'type': u'SpaceCharacters'}]
>>> list(walker.text(' abc ')) # doctest: +NORMALIZE_WHITESPACE
[{u'data': ' ', u'type': u'SpaceCharacters'},
{u'data': u'abc', u'type': u'Characters'},
{u'data': u' ', u'type': u'SpaceCharacters'}]
:arg data: the text data
:returns: one or more ``SpaceCharacters`` and ``Characters`` tokens
