- feature: the driver tries now to guess the appropriate codepage and sets it automatically

- as an alternative you can force the codepage with the old API

Printing text right
|
||||
-------------------
|
||||
Python-escpos is designed to accept unicode. So make sure that you use ``u'strings'`` or import ``unicode_literals``
|
||||
from ``__future__`` if you are on Python2. On Version 3 you should be fine.
|
||||
|
||||
For normal usage you can simply pass your text to the printers ``text()``-function. It will automatically guess
|
||||
the right codepage and then send the encoded data to the printer. If this feature should not work, please try to
|
||||
isolate the error and then create an issue.
|
||||
|
||||
I you want or need to you can manually set the codepage. For this please use the ``charcode()``-function. You can set
|
||||
any key-value that is in ``CHARCODE``. If something is wrong, an ``CharCodeError`` will be raised.
|
||||
After you have set the codepage manually the printer won't change it anymore. You can get back to normal behaviour
|
||||
by setting charcode to ``AUTO``.
