When parsing some fonts and trying to get namedVariation. it throws the following error:
TypeError: Cannot read property 'en' of undefined
When printing the instance where the undefined is raised it shows the following, name is missing.
{ nameID: 2, flags: 0, coord: [ 0, 400, 100, 0 ], postscriptNameID: 6 }
I dug a bit and the issue is cause because when getting the instance name is not fnding id 2 since name.records.fontFeatures starts at ID 256. When instance name matches with font ID 2 will use that, it seems this is very common and allowed by the spec:
The subfamilyNameID field provides a name ID that can be used to obtain strings from the 'name' table that can be treated as equivalent to name ID 17 (typographic subfamily) strings for the given instance. Values of 2 or 17 can be used; otherwise, values must be greater than 255 and less than 32768. The values 2 or 17 should only be used if the named instance corresponds to the font’s default instance.
