I´m Braziliam, so I want to put some symbols on my squiffy text like: ã, Ç, é, ó, etc. but when i put that symbols they show some strange thing like: é, ã, how can I fix it?

This is fixed in the next version of Squiffy.

Until that's released, you can either copy and paste your game file into the online version, or you can manually edit the index.html file that Squiffy generates to fix the problem.

Change the line

    <script src="story.js"></script>

to

    <script src="story.js" charset="UTF-8"></script>

tanks! I will use the Squiffy 5.0 now on
