Missing "missing character" warning

Missing "missing character" warning

[Marco Pessotto]

Hello all.

Reading the manual “Fonts in ConTeXt” I found the following statement
(p.97):

“In both cases we end up with a message in the log file and a resulting
file with missing data”. [When the font doesn't provide a glyph].

Now, the only case when the warning is issued is using mkii with xetex
(texexec -xtx), not with mkiv. (Unsurprisingly, the file with missing
data is always there :-)

Minimal example:

%% start
\mainlanguage[hr]

\starttext
Ja sam sȃm, i sȃm sam došao da izvršim pravdu.
\stoptext
%% stop

The name of the char is: LATIN SMALL LETTER A WITH INVERTED BREVE (0x0203)

So: 

$ context prova.tex

$ grep -i -E '(warn|miss)' prova.* 
[ match nothing ]

$ texexec --xtx prova.tex

$ grep -i -E '(warn|miss)' prova.*
prova.log:Missing character: There is no ȃ in font [lmroman12-regular]:+liga;+kern;mappi
prova.log:Missing character: There is no ȃ in font [lmroman12-regular]:+liga;+kern;mappi

It's not a regression, since the behaviour is the same with the last
year ConTeXt.

Best wishes

You can add this:

\checkcharactersinfont

and get missing characters reported to the terminal. Unfortunately I 
forgot () when adapting this command to the command namespace ...

\unexpanded\def\checkcharactersinfont 
{\ctxcommand{checkcharactersinfont()}}

(fixed in next beta)

After a lot of mumbling by myself... Is there a reason not to have the
fonts.missing tracker enabled by default? Performance hit?

indeed but you can enable it in your local cont-sys.tex file or in your 
texmfcnf.lua additions

Still, given the large amount of data that gets printed during a
compilation (it is basically impossible to figure out if something
goes wrong without carefully looking at the log), I would also support
the idea to print missing characters by default.

I'm also contemplating a different idea (after TL): wouldn't it be
nice if ConTeXt (luatex) would print warnings (missing image, missing
module, missing character, ...) in colour (if that's supported), to
make it clearly stand out from the rest?

clang and CMake use that regularly for example.

one can configure that locally ... much functionality only kicks in when 
really used (thereby limiting the overhead) and in that case messages 
also get suppressed till they make sense

i once played with it (1) but such a thing will only work on a console 
that supports ansi escape sequences (and console output of tex is 
already rather slow and flushing being character based it might give 
problems)

Hans

(1) in pdftex times ... it failed due to thsu ^^ escaping that tex applies
