If you're refrring to

Could this be a limitation of the character set being used in messaging (i.e. accented characters may not exist, or have different code values than what you're expecting) ?
Perhaps it may be possible if you could specify the character set (e.g.. something like specifying codepage) ? This of course would assume that you're selecting character set that receiver's device is able to display.
Of course, if we're dealing with different character sets -- another curveball that could be thrown would be faulty translation table (I do remember running into faulty ASCII/EBDDIC translation tables -- annoyingly often-mangled characters were caret, curly-braces and backslash -- which meant C programs would get mangled
