I'm trying to make flags for all my fictional countries. On some of these flags, it makes a great deal of sense to use a crest, similar to the real flags of Andorra and Spain. A lot of these crests use words as an integral part of the crest.
I would like to make crests like these, but I realized that (considering it was a fantasy world) it makes no sense to use the latin alphabet, or any real alphabet for that matter. I was wondering; would using the Latin alphabet to write a message (written in a fictional language) make any sense at all?
I have no plans to start constructing an alphabet. It would be a considerable amount of work for a very small issue and the story and world-building doesn't rely on it at all.
In a fantasy world, there's no good reason that the characters would end up similar, but it seems like a waste of time to create an entire alphabet just for the use of crests on flags. I'm wondering how to proceed.
So I was wondering if it makes any sense to use a real alphabet. The language would be fictional, as that is fairly easy (throw a few syllables together) but the alphabet would be latin, which realistically makes no sense for a completely removed setting. Does it make sense to use real alphabets for fantasy languages on map or emblems?
