.. _lang-unsignedchar:

``unsigned char``
=================

An unsigned version of the :ref:`char <lang-char>` data type.  An
``unsigned char`` occupies 1 byte of memory; it stores an integer from
0 to 255.

Like an :ref:`unsigned int <lang-unsignedint>`, an ``unsigned char``
won't store negative numbers; it is also subject to the same
:ref:`overflow issues <lang-int-overflow>` as any integral data type.

Example
-------

 ::

        unsigned char c = 240;
