Essel's post reminds me of the young couple who were touring Wales an ended up in Machynlleth. They went into a café for a bite to eat and the young man said to the waitress, "Can you tell us how to pronounce the name of where we are?"
She replied, " BUR-GER- KING".
They all have vowels, well vowel sounds at least otherwise they could not be spoken. That does not mean they have to use aeiou or even any of the arabic letters.
There are some languages where R and L are used in the place of some vowels. They are pronounced somewhere between the sound of a vowel and the sound of a consonant, and are called "vocalic R" and vocalic L"
Maybe letters that we see as vowels are different in other languages. Welsh, for example, has w sounding roughly like "oo" and y is commonly used as a vowel sounding like uh.
