I have an issue deleting selected area in Photoshop.
I use pen tool -> make a selection -> set 0px feather, +anti-alias ->
And I have a result like below:
Am I missing something to get straight and accurate edges ?
Maybe that's relative to some sort of pixels snaping?
UPD. Without anti-alias:

Yes, you are missing something - a piece of crucial information.
Photoshop is a raster image editor - and all raster images are made of pixels, and if you zoom in on the pixels, then you will see them.
Your first image shows what anti-aliasing looks like when zoomed in.
Your second image shows what it looks like when you don't use anti-aliasing.
All of this is perfectly normal, and everything is working perfectly as it should. There are no problems here at all.
To see the image as it will appear in reality, or in a browser etc, set the zoom level to 100% in Photoshop.
This is called anti-aliasing and yields a better, smoother result when you zoom back out. If you don't want those half-transparent pixels, you should deactivate the anti-aliasing option when selecting.
Exactly straight edges are only possible in Photoshop when those edges are exactly horizontal or exactly vertical (or maybe if exactly 45°). The nature of a pixel image is a raster of square pixels, so any slope needs to be simulated with anti-aliasing like this.
