Source Code shows as rectangles instead of charactars [message #678811]

Hello,

I've a very weird problem:

after upgrading from Ubuntu 9.04. to 11.04 (new installation), I have weird problems with the Eclipse editor.

When writing Java code (new Project was created) I type

System.out.println("bla")

and then "out" is shown as rectangles only. Weird is that for about half a second I see "System.out.println" and then the editor changes it to System.[][][].println (not really [] (here I used two brackets), it is shown as rectangles).
See the attached file for an example.

This is very weird. I've never had this before with any Ubuntu, Java or Eclipse version.

Currently, I use: Ubuntu 11.04. Eclipse 3.6 (latest download from June 7th) and Java 1.6.0_25.

Eclipse and Ubuntu Terminal is set to UTF-8.

The problem also happens when using KDE instead of Gnome.

Any ideas what could be wrong here and how to fix this?

I think that usually indicates that those characters were written in a
different charset than what the display can handle.

Verify that you do not have the file (through the Eclipse properties
dialog on the file) have a strange character set.

I checked the file.

It says Default (inherited from containter), UTF-8.

My locale on Linux says:

$ locale
LANG=en_US.UTF-8
LANGUAGE=en_US:en

$ echo $LANG
en_US.UTF-8
$ echo $LANGUAGE
en_US:en

So everything looks like UTF-8 which should be fine.
This also happens with completely new files (after creating a new class, for example).

I did another test. I copied the text with the rectangles and pasted it into gedit. There it looked correct and I saw "out" instead of rectangles.

event stranger:

When I type:

Syste.out.println("bla"); // leave out "m" in System

it shows correctly. The very moment I add that missing "m", "out" turns into rectangles.

Another weird thing. This source code looks correctly as long as it doesn't compile because of syntax errors.
But after it compiles correctly "out" turns into rectangles. I can now see this on several computers with the latest Eclipse and Java versions. I think this is a bug.

I figured it out. It was a font problem. Somehow Eclipse cannot display the standard font (maybe Ubuntu does not install that font anymore).

When changing the font, everything looks ok again.
