I just lost part of my weekend because of this … joker – zero width space. I just used some snippets from google groups and didn’t recognize that there are doubled characters, because Idea (11) didn’t show them, which was causing problems with parsing config file of my app… I discovered it accidentally in vi.
Is there any way to display such things in IntelliJ (or some other way to examine files) without using external editors.
IntelliJ 11 / Mac OS 10.7
edit – sample
These two lines looks identical, in browser and also in Idea. You can see in page’s code that in first – commented line there is hidden zero width space between mysql:// and localhost, which causes problems. Of course if you expect that ‘joker’, you can try to use search and replace it, however nobody expects the sign that should not be there, especially if he cannot see it in any way.
