Hejaz
Historically, the Hejaz has always seen itself as separate from the rest of Saudi Arabia. The Hejaz is the most populated region in Saudi Arabia; 35% of all Saudis live there. Hejazi Arabic is the most widely spoken dialect in the region. Saudi Hejazis are of ethnically diverse origins.
Arabic Braille
Arabic braille includes numerous abbreviations, some marked by dot 4 or dot 5 (the comma), which are not described here. A conference in Saudi Arabia in 2002 set up a unified braille standard for Arabic, but as of 2013 not all countries had signed up; those not adopting the standard include some Arab countries but also non-Arab Muslim countries such as Iran, Malaysia, and Indonesia.
