Character constants can be used to change the font style in TEXT
(:class:`alphasign.text.Text`) and STRING (:class:`alphasign.string.String`)
files.

--------------
Character sets
--------------

The following character set constants are defined:

* :const:`FIVE_HIGH_STD`
* :const:`FIVE_STROKE`

* :const:`FULL_HEIGHT_STD`
* :const:`SEVEN_SHADOW_FANCY`
* :const:`FIVE_WIDE`
* :const:`SEVEN_WIDE`
* :const:`SEVEN_FANCY_WIDE`
* :const:`WIDE_STROKE_FIVE`

The following character sets are available only on Alpha 2.0 and 3.0 protocols:

* :const:`FIVE_HIGH_CUST`
* :const:`SEVEN_HIGH_CUST`
* :const:`TEN_HIGH_CUST`
* :const:`FIFTEEN_HIGH_CUST`

The following character attribute constants are defined:

* :const:`WIDE_ON`
* :const:`WIDE_OFF`
* :const:`DOUBLE_WIDE_ON`
* :const:`DOUBLE_WIDE_OFF`
* :const:`DOUBLE_HIGH_ON`
* :const:`DOUBLE_HIGH_OFF`

* :const:`FIXED_WIDTH_ON`
* :const:`FIXED_WIDTH_OFF`
* :const:`FANCY_ON`
* :const:`FANCY_OFF`
* :const:`AUXILIARY_PORT_ON` -- Series 4000 & 7000 signs only.
* :const:`AUXILIARY_PORT_OFF`
* :const:`SHADOW_CHARACTERS_ON` -- Betabrite model 1036 and AlphaPriemere 9000 signs only.
* :const:`SHADOW_CHARACTERS_OFF`

-----------------
Character spacing

The following character spacing constants are defined:

* :const:`PROPORTIONAL` -- default
* :const:`FIXED_WIDTH` -- fixed width left justified

Examples

Make a text file using the :const:`FIVE_WIDE` charset::

  msg = alphasign.Text("%sthis is wide" % alphasign.charsets.FIVE_WIDE,
                       label="A")
