An unwonted warning I constantly get about fontsets when I start Emacs

An unwonted warning I constantly get about fontsets when I start Emacs

[Göktuğ Kayaalp]

Hi,

Since when I switched to using Emacs master as my daily driver (w/o any
real problems until now, ~in about a month I guess), whenever I start
Emacs, I get this warning:

Error (initialization): Creation of the default fontsets failed: (error Invalid script or charset name: old-italic)

My custom fonts are those which I used with 24.3 and 25.1 without any
issues like this.  And I do use some of my custom fonts for my visuals
configuration and they work.  I don't understand whether this is
sth. normal that I somehow triggered, or that I am facing a bug here.

Thanks in advance,

	gk.

Please show your fontset-related customizations.

I don't have any such customisations in Emacs.  Just setting the font
for some faces here and there:

Strange, I don't see old-italic mentioned anywhere.

Are you sure you don't have some stale Lisp files lying around and
shadowing the ones which come with the distribution?

Also, do you see this problem with "emacs -Q"?

None of my lisp files contain the word `fontset'.  I've looked quite a
bit, but haven't found anything related.  I just learnt what it is,
actually.

> Also, do you see this problem with "emacs -Q"?

Yes.  The message comes up in the *Warnings* buffer with or without -Q.
No problems with any functionality so far tho, just the warning.

This becomes more and more stuff for a bug report, not for discussion
here.

The old-italic script is defined in charscript.el, so check that file
for problems (damaged, truncated, outdated).  It is then used in
fontset.el, and the error you see comes from there, see the function
create-default-fontset.  Maybe by looking into these two files, or by
searching your system for outdated versions which shadow these, you
will find the culprit.

My next suggestion is to make sure the tree where you build Emacs is
clean, and doesn't contain any stale files from the previous versions
you've built.

charscript.el seems alright, it's installed only as an elc file, and
seems okay (I've diffed the .elc in the git repo with the installed
copy, no differences, then I recompiled the repo version via
‘byte-compile-file’, and diffed again, no differences).

In fontset.el, ‘old-italic’ appears in function ‘setup-default-fontset’,
called by ‘create-default-fontset’.  There, after the call to
‘new-fontset’, there's a dolist expression commented «For simple
scripts», which runs this expression on a list of symbols including
‘old-italic’:

(set-fontset-font "fontset-default"
                    script (font-spec :registry "iso10646-1" :script script)
                    nil 'append)

I tried this:

(let ((script 'old-italic))
  (set-fontset-font "fontset-default"
                    script (font-spec :registry "iso10646-1" :script script)
                    nil 'append))

Which gave me this backtrace:

Debugger entered--Lisp error: (error "Invalid script or charset name: old-italic")
  set-fontset-font("fontset-default" old-italic #<font-spec nil nil nil nil iso10646-1 nil nil nil nil nil nil nil ((:script . old-italic))> nil append)
  (let ((script (quote old-italic))) (set-fontset-font "fontset-default" script (font-spec :registry "iso10646-1" :script script) nil (quote append)))
  eval-region(146 322 t #[257 "\300\242b\210\301\207" [(322) (let ((script (quote old-italic))) (set-fontset-font "fontset-default" script (font-spec :registry "iso10646-1" :script script) nil (quote append)))] 2 "\n\n(fn IGNORE)"])  ; Reading at buffer position 146
[...]

The only emacs installation on my system is that one from the git repo
which I use daily, and this is the first build I made from this clone of
the repo.  It't virtually impossible that any shadowing happens.  Git
does not report any modified files.

As above.  I'll report this as a bug if you tell me to do so.  I'm
attaching charscript.el as it seems to be a generated file not tracked
by git.

What does the following produce in your Emacs:

  M-: (aref char-script-table #x10301) RET

> The only emacs installation on my system is that one from the git repo

The command list-load-path-shadows will produce a list of shadowed
files, if there are any.  (report-emacs-bug invokes that command
internally and includes its results in the bug report, which is one
more reason to use report-emacs-bug for such matters.)

I meant something like "git clean -x -f -f".  Or maybe clone the
repository anew.  These things are hard to detect by looking, and a
single stale file can drive you mad with its implications.

I think it's long overdue.

And here's what seems to be the root cause of your problem:

    (#x10300 #x1032F old-ıtalic)

That ı in ıtalic is the dotless i character, whereas it should be the
Latin i character.  I see a few more of those elsewhere in the file,
all of them will cause similar problems.  I'm guessing that some bug
causes this in your locale, so as the first thing please delete this
file and let the Emacs build process re-generate it, in the hope that
the bug was meanwhile fixed.  If the regenerated file has the same
problem, please do report a bug about that.

And I think I know what causes that: this file is produced by running
Awk, and the Awk program uses 'tolower', which in your locale produces
the dotless i characters instead of the Latin i.

So running the build after setting LC_ALL=C should fix the problem.

I'll try that now and report, but that seems a bit improbable to me as
this is my locale setup:

$ locale
LANG=en_GB.UTF-8
LANGUAGE=en_US
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC=tr_TR.UTF-8
LC_TIME=tr_TR.UTF-8
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY=tr_TR.UTF-8
LC_MESSAGES=en_GB.UTF-8
LC_PAPER=tr_TR.UTF-8
LC_NAME=tr_TR.UTF-8
LC_ADDRESS=tr_TR.UTF-8
LC_TELEPHONE=tr_TR.UTF-8
LC_MEASUREMENT=tr_TR.UTF-8
LC_IDENTIFICATION=tr_TR.UTF-8
LC_ALL=

If this and the other recommendations from your other message don't fix
the problem, I'll report a bug.

As I said in my other post, I'll try these and if it persists I'll
report a bug.

I've tried this:

git clean -x -f -f
./autogen.sh all
./configure --prefix=$HOME/local --with-x-toolkit=yes --with-modules \
	    --with-file-notification=yes --with-mailutils ;
LC_ALL=C make
./src/emacs -Q

And this has fixed the problem (i.e. no warnings anymore, built today's
master).  So now I'm not sure if this is a bug that I've triggered, or a
mistake in my build procedure.  If I'm not told otherwise, I'll file a
bug report when I have time.

Please try this:

  . go to the admin/unidata directory of the Emacs source tree
  . type the following command from the shell prompt:

     make -W Blocks.txt

This should regenerate lisp/international/charscript.el.  Please see
if it has the same problem with dotless i you had originally.  If it
does, then repeat the same command, this time setting LC_ALL=C, like
this:

     LC_ALL=C make -W Blocks.txt

This should again regenerate charscript.el, but with the correct
script names, using the Latin i letter.

If indeed you see what I describe above, please file a bug report with
this information.  Thanks.

I've tried these, and curiously could not reproduce the issue.  I'll
guess that something funky happened with my previous build, though I
don't have no idea about what that might be.  I did do multiple builds
from different checkouts until today with these results.

Well, please excuse me for the trouble.  I'll keep an eye on this in my
later builds and file a but if somehow it repeats.

Best,
