Hi, @THausherr !
Several possible performance improvements. Inside
GlyphSubstitutionTable.readScriptList method we create a scriptTables variable.
Then we fill it in loop. We then use it in the next loop. We can do this in the
first loop and remove this variable.
The same about the langSysRecords variable in the readScriptTable method.
You able to instantiate a regular exprestion one time to not do it for each
iteration in readFeatureList method (Pattern pattern =
Pattern.compile("\\w{4}")).
