Re: WOFF2 and 'meta' table

We can definitely revisit the list of known tables and see if anything there could be eliminated / swapped for 'meta' tag, but for all intent and purposes the list has nothing to do with how compression is applied, it only helps to save some bytes by reducing the size of the table directory.

Any arbitrary table that is not "known" would be represented in the table directory by the 'arbitrary' flag followed by the table tag, the table data itself will be a part of the compressed data stream regardless of whether it's known or not.

Thank you,

Apple defines 'meta' table that is still outside of OpenType spec. It contains information about languages font supports and designed for. We in Windows 10 decided to add this table to our system fonts and are in process of doing so.

I noticed that this table is not in the list of known table tags (http://www.w3.org/TR/WOFF2/#table_dir_format) and this may be the only real world table that is not compressed by this mechanism. Can we consider adding this table to the list? I know that list is currently full, but maybe we can replace some rarely used table with it?

Thanks,
