Hi Fumito,

It is indeed a great idea. As the default configuration won't use it anyway, it can be added with no hesitation.

Please feel free to make a PR to add this into the Core.

Add Japanese URL filtering to friendly_slug
By Fumito MIZUNO , 13 September 2014


I created a URL filtering which covers Japanese chars.



Is this a good idea to add this code into core's  framework/config/friendly_slug.config.php ?
