Marco,
This is a known issue with pre-OS X AAT fonts that have ligatures
designed for QD GX turned on by default.
AppKit has a workaround not to show this issue, but ATSUI apps are
affected by this problem.

Has no one ever noticed this weird bug, when an "o" followed by an "/"
gives this overlapped glyph "x" (pretty sure you wont see that one
here in the list). Well you know, this skandinavic umlaut, the striked
"o". Backspace deletes only the "/" part of the thing, so its
definitly two seperate characters just placed right ontop of each
other. It happens for me in Terminal with Monaco selected.
It also happened in other apps with Palatino (i think, or Bookman).
Very strange. I couldnt track it down (ok, I havent spend too much
effort to do so).

This occurs with a few more fonts try to type 'gg' and change the
font to
'Papyrus' and size to 288. See the first 'g' is chopped off ,
moreover
they overlap too.
It happens with a few more fonts but with different characters.

Is this a known bug that when you try to draw a huge 'j' letter
with the
AppKit, you get an improper result.
Do you? I don't.
Example:
1) Launch TextEdit.app
2) Type: JJoy of Tech
3) Select the text and set the font to be Lucida Grande 288.
And then compare the J on the left to its neighbour. Looks like the
first
J is on horizontal diet.
When I try here (10.1.5), I get both J's exactly the same; only with
Lucida Grande there seems to be a metric problem, which causes the
left
edge of the J to be somewhat into the letter, actually. Just try
that, try
also to place a space (or even better a letter, say, 'a') before the
first
J, and also try to select the J.
We're seeing this bug with [NSString drawAtPoint: withAttributes:];
too.
Do I need to file a bug report or is this a known issue (which is
also in
10.1 AFAIK)?
Can't say for sure, but this definitely looks as a specific problem
of the
metrics inside the Lucida Grande font (no such problem with
Helvetica or
Times; I haven't tried others). I haven't slightest idea whether it
was
reported or not.
