Ligatures with Accented Characters

timotheus

What, if any, accented characters (i.e., glyphs with diacritical marks such as Aacute or tcaron) are found in combinations that are commonly covered by ligatures? For example, c_t is a somewhat common ligature to include in well-rounded OpenType fonts. Would it also make sense to have c_tcaron or c_tbar? What about L_Aacute in an all-caps font that includes an L_A ligature?

I am looking for guidance, because I'm just not yet familiar enough with some of the languages that use these diacritics. I would appreciate any help. Pointing out useful references on the topic would be especially helpful.

Thanks, all.

Thanks. There's some good discussion there, but it's mostly around handling colliding accents. I'm more interested in ligatures coverage across languages.

Taking c_t as an example: if I were to include a c_t ligature in a font and also wanted to provide glyphs across the Latin ranges, should I also then include ligatures for ccedilla_t, c_tcaron, c_tbar, etc.? I am not sure what combinations are even possible across all the different languages. I don't think ccedilla_t actually occurs in reality, so there would be no need to include such a ligature. I'm just not sure which combinations are possible.

Just a few discretionary ligatures lead to a significant range of accented possibilities. Consider: s_t, c_t, o_o, s_p, T_h, L_A, N_N, R_A, T_T, T_Y....

Tim,

Check out 'Context of Diacritics' by Ondrej Jób, it should help you.
