Is there a way to find the code point of a specific character in the text editor?

This sounds like a pretty basic and very useful functionality but I can't find it.

Thanks for your help,

BR

The characters that the editor shows are in Unicode, so I don't quite
understand your question. Do you mean what encoding the file on disk has?

When I open a utf-8 encoded file in eclipse, ideally I'd like it to show me the codepoint (e.g. U+0660) of the character the cursor is placed on. Or at least, give me a way to find out its codepoint.

I see. There's nothing in the SDK that does this for you but it
shouldn't be too hard to implement this on your own.

Bob,

Java's character representation is effectively like UTF-16. You'd need
to use Java itself to deal with the relationship between surrogate pair
characters and the code point they represent, i.e.,
Character.isHighSurrogate/isLowSurrogate, and methods like
Character.codePointAt or the corresponding String methods dealing with
code points.
