looking for a UTF-8 text editor

Question

I am looking for a (simple) text editor that can handle text in different encodings in the same document.

I need to develop some sites with mixed Japanese and Englis

Answer 1

It sounds like maybe the problem with Jedit is the font - are you using a font that can display all the characters correctly?

To be more precise, Arial Unicode MS is a reasonable choice for a Unicode font that can display a wide range of characters across the range of languages. There are certain issues with it that can make it less than optimal for some languages used in isolation - this is why there are also language specific Unicode fonts included with Windows.
