    With short ascenders and a very high x-height, Poly is efficient in small
    sizes. Thanks to its careful balance between the x-height and glyph widths,
    it allows more economy and legibility than standard web serifs, even in
    small sizes. The aglutinative language for which it was designed contains
    very long words. The goal was to develop a typeface that would tolerate
    cramped tracking and that would increase the number of letters on a single
    line. Poly is a Unicode typeface family that supports Open Type features
    and languages that use the Latin script and its variants.
