ActionScript 3.0 :: ToUpperCase For Non-standard Characters

We've got an issue (minor, but annoying) that I've got no clue where to begin to tackle.Our video player is run off a backend database, and 2 characters in particular are giving us problems:which are saved into the database with their ISO Latin-1 codes to avoid compatibility issues (ha, imagine that!).Now, all is fine and dandy except that our player uses this particular piece of data as a header in the template, styled to all caps using toUpperCase, which breaks the whole thing because it seems toUpperCase cannot properly map these letters to a corresponding uppercase value. To get around this we've tried using the HTML code for the uppercase equivalent of the same letter but the problem with this is that this same exact piece of data is also used on our website, but in it's raw camel-case format. We can't force it one way or the other, because then it breaks the other.

Is there a way we can use these sort of characters in both instances (in Flash with toUpperCase, and in the HTML page as camel-case)? Is this a Flash issue? A character code issue? A database issue? Where do I begin to address this?
