Issue

In v2.000, if two U+0633 ARABIC LETTER SEEN (س) or U+0634 ARABIC LETTER SEEN (ش) came together (or if one is followed by the other), then the first س or ش would be replaced with a nice swash variant.

This has stopped working since v2.001. Please bring the swash س/ش back. 🙂

v2.000:

Since v2.001 (here shown in v3.002):

Note that for some sequences (like سسر), the swash does appear. The swash(es) also appear if more than two س or ش come together (as in سسس, and as detailed in #22 and #24.)

Thanks for fixing this! Found two regressions, though, in the following strings:

سس شش
سسر ششر
