By default, Vermont Views does not support proper use of the extended character set, that is, any characters with keycodes 128 to 255. The default settings do not allow the user to enter any extended characters, which include international alphabetic characters, block graphic characters, and mathematical symbols, in data entry fields. Also not supported is the proper upper- and lowercase conversion of characters in this range.
To enable support for the extended character set, you must #include the extended character header file in your main program. For example:
|
The vv_extch.h header files contains an uppercase/lowercase conversion table for the extended characters and enables use of these characters in data forms.
