Therefore, Iosevka and Iosevka Slab all contain two specialized families, *Term* and *Fixed*, targeting terminal users. In these families, the symbols will be *narrower* to follow terminals’ ideology of column count. In the Fixed families, the ligation will be disabled to ensure better compatibility in certain environments. ### Iosevka *∑* { *n* ∈ *▲* } *🅇*(*n*) *○->* *Ⓨ*\[*n*\] *▢△◈* ### Iosevka Term *∑* { *n* ∈ *▲* } *🅇*(*n*) *○->* *Ⓨ*\[*n*\] *▢△◈* ### Iosevka Fixed *∑* { *n* ∈ *▲* } *🅇*(*n*) *○->* *Ⓨ*\[*n*\] *▢△◈* Iosevka provides *146* configurable characters with *19* stylistic sets, which gives you incredible ability to customize one variant that fills exactly what you need.

Enable the corresponded OpenType feature in your editor, and the correct ligation will appear.
