/**
 * charset - character set conversion and validation routines
 *
 * This module provides a collection (well, only one, at the moment) of
 * well-tested routines for dealing with character set nonsense.
 *
 * Validation functions:
 *  - bool utf8_validate(const char *str, size_t length);
 *
 * Example:
 *	#include <err.h>
 *	#include <stdio.h>
 *	#include <string.h>
 *	#include <ccan/charset/charset.h>
 *	#include <ccan/grab_file/grab_file.h>
 *	#include <ccan/talloc/talloc.h>	// For talloc_free()
 *
 *	int main(int argc, char *argv[])
 *	{
 *		size_t len;
 *		char *file;
 *		bool valid;
 *
 *		if (argc != 2)
 *			err(1, "Expected exactly one argument");
 *
 *		file = grab_file(NULL, argv[1], &len);
 *		if (!file)
 *			err(1, "Could not read file %s", argv[1]);
 *
 *		valid = utf8_validate(file, len);
 *		printf("File contents are %s UTF-8\n", valid ? "valid" : "invalid");
 *
 *		talloc_free(file);
 *
 *		return 0;
 *	}
