why do foreign accent marks in texts make the whole text disapear?

[machek]

Does anyone know why when I write something in a text with foreign accent marks and send it in a text to someone, some people never get the text, some people get a blank text and some people will get the whole thing with the accent marks included? Does anyone know if this is an easy fix or does it depend on the phone that that person has? My two friends wont get it, one with a lg env touch, the other a blackberry, and the one that gets it is a Razor. WTF. It kinda sucks. Any info would be appreciated. Oh and I'm with Verizon, the two that didnt work were verizon to verizon, verizon to tmobile, and the one that did work verizon to verizon on the razor. Thanks
