Possibly related to #105 ?
from lib-font.

I've slightly changed the test code to not single out lookup type 6:
function testFont(font) {
const { GSUB } = font.opentype.tables;
const scripts = GSUB.getSupportedScripts();
let allGlyphs = {};
scripts.forEach((script) => {
let langsys = GSUB.getSupportedLangSys(script);
allGlyphs[script] = {};
langsys.forEach((lang) => {
let langSysTable = GSUB.getLangSysTable(script, lang);
let features = GSUB.getFeatures(langSysTable);
allGlyphs[script][lang] = {};
features.forEach((feature) => {
const lookupIDs = feature.lookupListIndices;
allGlyphs[script][lang][feature.featureTag] = {};
allGlyphs[script][lang][feature.featureTag]["lookups"] = [];
lookupIDs.forEach((id) => {
const lookup = GSUB.getLookup(id);
lookup.subtableOffsets.forEach((_, i) => {
console.log(
`Getting subtable ${i}, lookup ${id}, feature ${feature.featureTag}, script ${script} , lang ${lang}`
);
const subtable = lookup.getSubTable(i);
});
});
});
});
});
}from lib-font.

Looking at getSubTable() and adding a try/catch:
getSubTable(index) {
const builder = this.ctType === `GSUB` ? GSUBtables : GPOStables;
this.parser.currentPosition = this.start + this.subtableOffsets[index];
console.log(`getSubTable(${index}): this.parser.currentPosition = ${this.start} + ${this.subtableOffsets[index]}`)
try {
return builder.buildSubtable(this.lookupType, this.parser);
} catch (e) {
console.log({
...this,
start: this.start
});
throw e;
}

Updating the GSUB lookup6 class:
class LookupType6 extends LookupType {
constructor(p) {
super(p);
console.log(`building GSUB lookup type 6 subtable, with substFormat ${this.substFormat}`);Shows:
...
Getting subtable 0, lookup 6, feature ccmp, script latn , lang dflt
getSubTable(0): this.parser.currentPosition = 4546 + 8

So let's investigate the code specific to 6.2
from lib-font.

And that might be a valid chainSubClassSetCount but it looks terribly suspicious

Time to break out the documentation: https://docs.microsoft.com/en-us/typography/opentype/spec/gsub#lookuptype-6-chained-contexts-substitution-subtable tells us that we also need to look at https://docs.microsoft.com/en-us/typography/opentype/spec/chapter2#chseqctxt2
Our table format should be:
| Type | Name | Description |
|---|---|---|
| uint16 | format | Format identifier: format = 2 |
| Offset16 | coverageOffset | Offset to Coverage table, from beginning of ChainedSequenceContextFormat2 table |
| Offset16 | backtrackClassDefOffset | Offset to ClassDef table containing backtrack sequence context, from beginning of ChainedSequenceContextFormat2 table |
| Offset16 | inputClassDefOffset | Offset to ClassDef table containing input sequence context, from beginning of ChainedSequenceContextFormat2 table |
| Offset16 | lookaheadClassDefOffset | Offset to ClassDef table containing lookahead sequence context, from beginning of ChainedSequenceContextFormat2 table |
| uint16 | chainedClassSeqRuleSetCount | Number of ChainedClassSequenceRuleSet tables |
| Offset16 | chainedClassSeqRuleSetOffsets[chainedClassSeqRuleSetCount] | Array of offsets to ChainedClassSequenceRuleSet tables, from beginning of ChainedSequenceContextFormat2 table (may be NULL) |
from lib-font.

In the subtable we see:
class LookupType6 extends LookupType {
constructor(p) {
super(p);
...
if (this.substFormat === 2) {
this.coverageOffset = p.Offset16;
this.backtrackClassDefOffset = p.Offset16;
this.inputClassDefOffset = p.Offset16;
this.lookaheadClassDefOffset = p.Offset16;
this.chainSubClassSetCount = p.uint16;But if we look at the super class, we see:
class LookupType extends ParsedData {
constructor(p) {
super(p);
this.substFormat = p.uint16;
this.coverageOffset = p.Offset16;
}So there's our bug: we're double-parsing this.coverageOffset, once in the super class, and then again in the specific class
from lib-font.

Removing the erroneous double parse from the LookupType6 class:
class LookupType6 extends LookupType {
constructor(p) {
super(p);
...
if (this.substFormat === 2) {
this.backtrackClassDefOffset = p.Offset16;
this.inputClassDefOffset = p.Offset16;
this.lookaheadClassDefOffset = p.Offset16;
this.chainSubClassSetCount = p.uint16;
this.chainSubClassSetOffsets = [
...new Array(this.chainSubClassSetCount),
].map((_) => p.Offset16);
}
...With updated test:
...
lookup.subtableOffsets.forEach((_, i) => {
const subtable = lookup.getSubTable(i);
console.log(
`Getting lookup ${`${id}`.padStart(2, ' ')}, subtable ${i}, lookuptype ${subtable.type}, format ${subtable.substFormat}, feature ${feature.featureTag}, script ${script}, lang ${lang}`
);
});
