Is the glyph there at all? Is it set to export? Does it have a proper Unicode value? But if you cannot find anything wrong with the glyph in question, chances are the problem is located immediately before. If it says, for instance, syntax error at "Udieresisgrave" in Class Uppercase, naturally, you will look and see if there is anything fishy about Udieresisgrave.

If that does not solve the problem, or if you have manual feature code, you will have to take a closer look at what exactly the error message says (again, the Error Handling section in the Handbook will be of great help here), and the exact spot the error message points to.īut careful: MakeOTF error messages sometimes miss the problematic spot.

If the code is automated (i.e., the Generate Feature Automatically option is on), try the Update and Compile buttons at the bottom of the Font Info > Features window. Glyphs will take you to the problematic spot in the feature code. If you have a Show button in the dialog, click on it. Especially if you have outdated or manual code in File > Font Info > Features, you may get a dialog titled MakeOTF Error, pointing to a problem in a certain line in the feature code: Syntax errors in the OpenType feature code are a special case. However, do read the tutorial about complex outlines and see if you can find more handy tips. With a simple custom parameter called Disable Subroutines, its value being on, in File > Font Info > Font, your problem may be solved. The most likely cause for the never-ending export is the subroutinization of outlines, which only works well and efficiently for simple and clean outline structures. You get the export dialog with the spinning symbol, and it just doesn’t stop? Like, you have been waiting for minutes already?Ĭhances are you are exporting a CFF font with complex outlines. There are a bunch of scripts that start with Remove Kerning, which may help you. Consider using the mekkablue scripts in the Kerning submenu. Go to Window > Kerning, and start getting rid of some your kerning pairs, perhaps compress kerning via the gear menu.Click on its Value, and add mark and mkmk on separate lines. In File > Font Info > Instances, in every instance that fails to export, add a custom parameter called Remove Features. Don’t worry, it will not affect your compounds. If you can, get rid of mark and mkmk features, which store information about combining-mark positioning.Add a custom parameter called Use Extension Kerning to File > Font Info > Font > Custom Parameters and turn it on.Try these steps in this order until the export works:
The most likely cause for the error is that you have too much kerning pairs, or kerning with large kerning groups and many group-exception and exception-group kern pairs. That include kerning and mark positioning. Now GPOS is the OpenType table that stores glyph positioning info, hence the name. Sometimes you will receive an error talking about a ‘GPOS Subtable Overflow’. There is also a detailed Error Handling chapter in the Glyphs Handbook describing the various messages that may appear.
Plus, we have been hard at work making Glyphs give you descriptive error messages if something goes wrong. Of course, your mileage may vary greatly. Now you know what to do: Go back into Glyphs and delete one of the Euros, then export again. This means that there are two Euro signs inside the font, one called euro, another one called Euro, and they both have the Unicode 20AC.
In this case, the line says, ‘multiple glyphs euro Euro mapped to code 20ac’.
