[quote author="Kenji @ CodeIgniter Users Group in Japan" date="1266063088"]CI should use 1.7.1's no double encoding code again.

This is right when we think comaptibility is more important.
But 1.7.2's code is clean and better when we think that to store an html string containing html entities in a DB is bad practice.
Because html entities are only needed in html output. If you store an html string containing html entities in a DB, you must decode html entities when you mail the data.
If you want to seach the data, you must convert your keyword to html entities.
If you use 1.7.1 code, a string like "& must be written as &_amp;" is not processed correctly. Oh, this forum also, I add "_" after last "&" intentionlally.
