[WARNING]s in the Output Panel I don't understand what they mean or how to fix

[fontdesigner2]

I can't find any information or help on this subject, and I don't see anything about this in the manual either.

When I generate my new font I get these [WARNING] messages and I don't know what I am supposed to do about them.

Does anyone know what these warnings in the output Panel mean or how to fix the problems? Thanks in advance!

1:
[WARNING] <myFontName> Pair positioning has two different values in 'kern' feature; choosing the smaller absolute value: Abreve
[WARNING] <myFontName> Pair positioning has two different values in 'kern' feature; choosing the smaller absolute value: Abreve

YES, IT SAYS THIS TWICE IN A ROW for some reason.

I get several of these duplicate warnings. About ten pairs or each problem glyph: Abreve, Aogonek, Emacron, Ebreve (there are 4 duplicates of that warning), Edotaccent, Eogonek, Ecaron, OE, Tcommaaccent, Tcaron, and Tbar.

2:
[WARNING] <myFontName> Start of new pair positioning subtable; some pairs may never be accessed: [A Agrave Aacute Acircumflex Atilde Adieresis Aring Amacron Abreve Aogonek] [S Sacute Scedilla Scaron ] [/Users/admin/Library/Application Support/FontLab/Studio 5/Features/fontlab.fea 3019]

I get tons of these warnings for various glyphs.

3: (This is not a warning. It's a note.)
[NOTE] <myFontName> Removing duplicate glyph <> [/Users/admin/Library/Application Support/FontLab/Studio 5/Features/fontlab.fea 3029]

I get tons of these warnings for various glyphs.

I think the messages are quite clear.
Remove all duplicate glyphs in your font and then re-check your kern feature in the OpenType panel.

Thanks for your help.

I'll start looking in the OpenType panel for problems in the kern feature, but I can't understand why it says I have duplicate glyphs. I'm using the standard MacOS Roman encoding. I haven't added or removed any glyphs that were already there, and I'm looking through all the glyphs and I see no duplicates.

The error doesn't mean you have duplicate glyphs in your font, it means you have duplicate glyphs in your kerning classes.

[Ray Larabie]

What Mark said. Open the Open Type Kerning assistance panel and click the yin/yang symbol to help track down problems. Also make sure there are no classes with identical names.

Thanks for your help guys.

Yep. You're right. The problem was in my classes. They were all messed up. This is my first font, and while I was working on it, I wound up really messing some things up. The only thing that finally fixed it for me was to go back to a previous version and copy and paste glyphs from the new one into that. From now on I will be more careful. Live and learn. Now I don't get any error messages, but I'm still copying and pasting and realigning glyphs right now.

Thanks again.
