Descripción

Este módulo provee una interfaz para el acceso a la base de datos Unicode.

La lista completa de submódulos acá.

Está basado en la versión del Wikcionario en inglés.

Se espera que con el presente módulo se puedan hacer fundamentalmente dos cosas:

  • Insertar automáticamente la tabla con información unicode de una página, siempre y cuando la misma consta de un único caracter. Esto se hace mediante la plantilla {{mostrar-unicode}}
  • Generar tablas con caracteres unicodes para clasificaciones en el espacio Apéndice.

Aún no está completa la implementación.

Sumas gracias a todos los usuarios que contribuyeron en el desarrollo del módulo para la versión en inglés.
