Which language would that be? I was curious
It's the Malay language. The Latin script is the commonly used one cause we were colonised.
We previously used an altered Arabic script (Jawi), but now it's used sort of like a liturgical script for Muslim literature and only some older generations still use it for general purposes because they're more comfortable with it. You do still regularly see Jawi on signage, it's basically just a telltale that the owner is Muslim if you're not in a state where the use of Jawi is state-mandated on signage.
In the northern states, which borders Thailand, there's a notable Siamese population which sometimes uses the Thai script, you can see some signs written in the Thai script read in the Malay language there. It's specific to their community and no other communities in the country uses the Thai script. In the southern states of Thailand you might find them though.
I've also seen people jokingly use Chinese characters to write but I can't really find information about it in literature so I assume it's purely a joke and was never a real thing
Tldr; the Malay language has three scripts, Latin, Arabic and Thai
