Kern feature error woes

Chris Lozos

Every time I try to build kerning classes, I get the following error with each class:

<<[WARNING] Start of new pair positioning subtable; some pairs may never be accessed: [A.smcp Aacute.smcp Abreve.smcp Acircumflex.smcp Adieresis.smcp Agrave.smcp Amacron.smcp Aogonek.smcp Aring.smcp Atilde.smcp] [Y.smcp Yacute Ycircumflex Ydieresis] [/Users/chrisL/Library/Application Support/FontLab/Studio 5/Features/fontlab.fea 1226]>>

What do I do now?

Don't kern :^)

Then I would have to throw away my KERN zipup from Veer :-)

Teach typography. Give your students the fonts with no kerning pairs. Tell them that they can only use those fonts for headlines, and imperfect kerning will lead to a failing grade.

Chris, see that thread: http://www.typophile.com/node/37959

"Then I would have to throw away my KERN zipup from Veer :-)"

I remember that thread, David. I thought I did follow the one-time-per class rule but I will check again.

Then I might be chasing rainbows :-)

Try looking at the small cap Y class. I think you want to change it from this

Y.smcp Yacute Ycircumflex Ydieresis

to this

Y.smcp Yacute.smcp Ycircumflex.smcp Ydieresis.smcp

;^)

Hahaha! Great.

(And if you kern a lot, also try the AFDKO Generate Kern Feature script.)

Thanks, everyone! It wasn't the Y class but I did find a few other misdeeds caused by my attempt to do search and replace functions on some of my other classes. The big screwup though was having OE and oe in 2 classes :-/

I am really getting sloppy-brained in recent months!

I wish There was a good tutorial on FL5 class kerning. Anyone know of one?

ChrisL

Anyone know of one?

Hello Mr Lozos! Meanwhile, all possible troubles have been dealt with on Typophile. What's needed is a summary ...  ;-)
I have a little script which checks kern classes for possible overlaps of content, and will update [required since the AFDKO kern feature script now allows for exception classes] and post it tomorrow. Too tired to do it now.

Thanks Karsten!

Sleep well!

ChrisL

I did!

You can download it here, it is called "Check Kern Classes". If something is wrong with class definitions, it shows a report in the Output Panel.

If you use the AFDKO 2 "Kern Feature Generator" script, you only need to define tags for leftside, rightside and/or exception classes there. Please see the .txt file for details.

Karsten,
Glad you had a good night's rest and hopefully a good hot dinner as well! Thanks, I 'll check it out.
