Hanunoo script
Hanunoo (IPA: [hanunuʔɔ]), also rendered Hanunó'o, is one of the scripts indigenous to the Philippines and is used by the Mangyan peoples of southern Mindoro to write the Hanunó'o language. It is an abugida descended from the Brahmic scripts, closely related to Sulat Tagalog, and is famous for being written vertical but written upward, rather than downward as nearly all other scripts (however, it is read horizontally left to right).
