HTML Character Entities

From Monket

Usage

Runs using the command line version of PHP.

Converts whatever text is given as Standard Input and returns it as Standard Output.

Code

<?php // -*- coding: utf-8 -*-

/*

Replaces Macrons (and other stuff) with HTML entities.

Converts non-ASCII characters to their HTML entity equivalents.
This includes Macrons, curly quotes, en- and em-dashes, and copyright symbols.

Also converts Word list markers to '*' characters, so that lists are in
a Markdown format.
