Changeing difficulty?

So, I play terraria on medium core. However, I've noticed that in some cases medium core sucks.
So, does anyone know how to change difficulty? It probably requires messing with the data file for your character, so any help?

The only way I know of is to make a new character and get all your stuff from a chest.

Making a new character or using InvEdit are the only ways

I believe there is an inv edit that allows you to change your character difficulty. Ill look into it
Edit:

Thanks, I play Vanilla, so I'll do this quick Thanks.

The non-English versions of Terraria are known to be buggy or prone to crashing, unfortunately. The developer has recently been soliciting ideas for an update, and I proposed addressing this issue. If you would like to add your voice to this, this is the latest suggestion thread: http://www.terrariaonline.com/posts/1979664/

Stash all your stuff in a chest, make a new char and grab it all.

The problem is with the language no with the character.
