**Iosevka** is an *open-source*, *sans-serif* + *slab-serif*, *monospace* + *quasi‑proportional* typeface family, designed for *writing code*, using in *terminals*, and preparing *technical documents*.
## Installation
Quit your editor/program. Unzip and open the folder.
* **Windows**: Download the fonts from the [Releases](https://github.com/be5invis/Iosevka/releases), select the font files and right click, then hit “Install”.
* On Windows 10 1809 or newer the default font installation is per-user, and it may cause compatibility issues for some applications, mostly written in Java. To cope with this, right click and select “Install for all users” instead. [Ref.](https://youtrack.jetbrains.com/issue/JRE-1166?p=IDEA-200145)

In the official package, Iosevka provides 6 monospace subfamilies (sans-serif and slab-serif, each in the 3 spacings Default, Term and Fixed) and 2 quasi-proportional subfamilies (Aile (sans-serif) and Etoile (slab-serif)). In all the monospace subfamilies, 9 weights (Thin to Heavy), 2 widths (Normal and Extended), and 3 slopes (Upright, Italic and Oblique) are included. In the quasi-proportional subfamilies, the quantity of widths is reduced to 1.
All versions include the same ranges of characters: Latin letters, Greek letters (including Polytonic), some Cyrillic letters, IPA symbols and common punctuations and some symbols. You can check out the full list [here](http://be5invis.github.io/Iosevka/specimen).

### Character Variants
Alongside stylistic sets, Monospace Iosevka can also be configured to cherry-pick variants for each character using OpenType. The variants are shown below. To enable, assign the feature tag to the variant index. For example, setting `cv26` to `6` will enable single-storey `a`.
**Caution :** Certain software may limit the quantity of OpenType features and drop some of them if the feature list is too long. Please validate your feature configuration to ensure that it worked in your software.

Iosevka supports Language-Specific Ligations, which is the ligation set enabled only under certain languages. These ligation sets are assigned to custom feature tags. To use them, you need to turn **off**`calt` and enable the corresponded feature. The feature list is:
Please note that, due to the complex interactions when forming ligations, cherry-picking ligation groups will require a custom Iosevka build. The instructions could be seen below.
