Allowed mask characters and function:
Character Function
# Allow numeric only (0-9)
N Allow letters (a-z,A-Z) and numbers (0-9)
A Allow uppercase letters only (A-Z)
a Allow lowercase letters only (a-z)
X Allow any typeable character
C Allow any letter, upper or lower (a-z,A-Z)
N Allow letters and numbers (0-9)
A Allow uppercase letters only
a Allow lowercase letters only
C Allow any letter, upper or lower
X Allow string.letters, string.punctuation, string.digits
Using these characters, a variety of template masks can be built. See the
demo for some other common examples include date+time, social security
Note:
These controls define these sets of characters using string.letters,
string.uppercase, etc. These sets are affected by the system locale
setting, so in order to have the masked controls accept characters
that are specific to your users' language, your application should
set the locale.
For example, to allow international characters to be used in the
above masks, you can place the following in your code as part of
your application's initialization code:
import locale
locale.setlocale(locale.LC_ALL, '')
Using these mask characters, a variety of template masks can be built. See
the demo for some other common examples include date+time, social security
number, etc. If any of these characters are needed as template rather
than mask characters, they can be escaped with \, ie. \N means "literal N".
(use \\ for literal backslash, as in: r'CCC\\NNN'.)
