The "name" parameter for #'make-frame

The "name" parameter for #'make-frame

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2002-05-29 on camaro
configured using `configure  --prefix=/tmp/e212 --with-xpm --with-jpeg --with-tiff --with-gif --with-png --with-x'
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: POSIX
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: en_US
  locale-coding-system: iso-latin-1
  default-enable-multibyte-characters: t

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Starting Emacs21.2 with --no-site-file -q, and using 
	 (make-frame '((name . "abc")))

	 gives an error: (error Font `fontset-16' is not defined)

Using "123" instead  of "abc" gives the same  error.  However, using a
string of  only accented characters  in iso-8859-1 succeeds!   Using a
string of traditional Chinese  characters succeeds!  Using a string of
a  mixture   characters  from   the  following  scripts   also  works:
traditional Chinese,  Thai, Tibetan, Korean  Hangul, Japanese Hiragana
and Katakana.  Mixing  in ASCII (yes, the 7-bit  subset of iso-8859-1)
letters sometimes works, but usually results in that error.


I discovered this when trying to use ediff, whose control frame failed
to      open     because      of      this     problem.       Changing
ediff-ediff-control-frame-parameters so that the "name" parameter does
not contain any ASCII characters can work around this bug.

Does it help to read the entry in etc/PROBLEMS whose header reads "Emacs 
fails to start, complaining about missing fonts"?

In a nutshell, I suspect your fonts are set up so that ASCII characters 
in a frame's name need some font whose fontset definition is incorrect or 
misformatted.

Yes.  I had  solved this problem before.  Emacs21  could start up.  It
just failed to create the tool-tip popups and new frames.

But why  does it default to "fontset-16"  instead of "fontset-startup"
or  "fontset-standard"?  (And I  already had  a "fontset-18".   I just
changed the  name to "fontset-16" and  it worked even  though the font
spec  still says 18-point  fonts.)  Is  this configurable  in ~/.emacs
(without having to add one statement for EVERY package)?

In my  case, "fontset-startup" is  smaller than "fontset-16"  (which I
want to be the  name of what it says: 16-point fonts).   And I find it
ridiculous that  the tool-tip text and  the text in  the ediff control
panel are bigger than the text in my main working window.
