Praveen,

The Rachana_w01 does not use ZWJ in the GSUB table(for chillus,ie).So
to avoid  unnecessary rendering of ZWJ the SF_PROCESS_ZWJ flag has to
be removed.Otherwise, include the ZWJ reference in the GSUB of the
font and use the SF_PROCESS_ZWJ flag.My patch uses the latter option.

On the indic unicode.org list I've been trying to keep track of which
scripts require ZWJ during the font GSUB lookup stage. What was the
justification for the removal of the SF_PROCESS_ZWJ from Malayalam
script flags?

With that option the ZWJ symbol was rendered unnecessarily. It render
well without that option.

Suresh,

you might want to comment on this.

Regards
Praveen
