When using the language select section in the funtoo wiki, languages such as Kazakh, Serbian, Tatar and more that are written in 2 scripts(mostly cyrillic and latin) appear in 2 entries, but are written in the same writing system with no indicator for the difference between the entries(only shows as a tooltip when hovering over the given entry). Examples are attached below(there are probably more than the ones in the images)

I also took a look at wikipedia, since we use the same underlying engine and for languages like Serbian and Kazakh, they just don't offer 2 options and instead show them as one, for example Serbian is listed as: "српски/srpski"
