Dear Bug Team!
I use the latest version of XEmacs together with Gnus to read
Usenet messages. Gnus shows some header values using an italic
font. At this point, it stroke me that the left side of the
upper half of some characters seemed to be cut. To make things
clearer, I extracted a screenshot showing the odd drawing of
characters.
I further noticed that I can use the cursor to "visit" each
character, which will also cause this type of cutting. This is
documented by the second screenshot.
This behaviour is not specific to Gnus, I also found this for
example in the customization buffer for faces.
Regards,
Franz Häuslschmid.

That's "right" side. Good thing you included the PNGs! :-)
X fonts don't specify italic corrections, and these italic fonts are
writing outside of their nominal bounding boxes. Not much we can do
about that in the context of the current redisplay engine, I'm afraid.
As a workaround, I suggest that you try a different font, even the
"same" family from a different foundry. If the bounding box is
defined to allow the _left_ side to project out of the box rather than
the _right_ side, there should be no clipping of this kind because the
text is always drawn left to right. Except perhaps at the very left
edge of the window, and XEmacs provides a way to leave extra space
there. (If you need it ask, I don't recall offhand.)

Uh, I must be a left/right dyslexic.

I'm on MS Windows here. Is the explanation above valid, too?

[...]
On my system, XEmacs Beta recently uses a different default font
than previous versions or the stable XEmacs used to. I set it
from `Lucida Console' to `Courier New' by manoeuvring through the
options menu. The section of `custom.el' that handles
`custom-set-faces' now looks like
,----
| (custom-set-faces
| '(default ((t (:size "10pt" :family "Courier New"))) t)
| '(font-latex-title-1-face ((((class color) (background light)) (:foreground
"blue4" :family "helvetica" :bold t))))
| '(font-latex-title-2-face ((((class color) (background light)) (:foreground
"blue4" :family "helvetica" :bold t))))
| '(font-latex-title-3-face ((((class color) (background light)) (:foreground
"blue4" :family "helvetica" :bold t)))))
`----
Normal text is now drawn using `Courier New'. However, text set
in a bold and/or italic environment still use another font and I
assume that it is the old default, `Lucida Console'.

Franz Häuslschmid.

Probably, but I don't know much about how this works in the MS world.
It's possible that we could get the italic correction and do something
about it systematically. I'll see if I can convince Ben or Andy to
look at it.

That was a deliberate change, but I don't know for sure what the
rationale is. I think it's a denser font, so you get more text on
screen for the same point size.
