Ensure soft_dotted characters lose their dot when combined with marks that replace the dot.

This is a new Google FB check.

🔥 FAIL The dot of soft dotted characters used in orthographies must disappear in the following strings: i̊ i̋ j̀ j́ j̃ j̄ j̈ j̑ į̀ į́ į̂ į̃ į̄ į̌ і́ The dot of soft dotted characters should disappear in other cases, for example: i̇ i̒ ị̇ ị̊ ị̋ ị̒ i̦̇ i̦̊ i̦̋ i̦̒ i̧̇ i̧̊ i̧̋ i̧̒ i̩̇ i̩̊ i̩̋ i̩̒ i̱̇ i̱̊ [code: soft-dotted]

@djrrb here is the recent FB issue and the ccmp fix.

So this link says that the ccmp code is optional, nor is it a complete and functioning example (there’s just an #etc. comment).

I’m hesitant to try to quickly hack together a ccmp that I don’t fully understand. @guidoferreyra is this something you think you could take a stab at, or since it says the code is optional do you think it makes sense to omit for now?

I’ve never used that specific solution since it’s quite new. But I’ve been using a similar, but not that much comprehensive, suggested by Glyphs App.

lookup ccmp_Other_1 {
    @CombiningTopAccents = [acutecomb brevecomb breveinvertedcomb caroncomb circumflexcomb commaturnedabovecomb dblgravecomb dieresiscomb dotaccentcomb gravecomb hungarumlautcomb macroncomb ringcomb tildecomb];
    @CombiningNonTopAccents = [cedillacomb dotbelowcomb macronbelowcomb ogonekcomb verticallinebelowcomb];
    sub [i j]' @CombiningTopAccents by [idotless jdotless];
    sub [i j]' @CombiningNonTopAccents @CombiningTopAccents by [idotless jdotless];
} ccmp_Other_1;
