Some names in other languages might be too difficult for the engine to pronounce, which would kind of suck for people with those names. For the taunts, you had to murder the spelling of some English words so that it would sound like what you wanted it to.Are these programs really so inflexible? Did they not just license an already made system? would there not be a latin language bank to license? Honestly I don't understand how these things work very well, but it doesn't seem like it would be hugely expensive to "localize"
