Before it's too late, I'd like to point out that for consistency, the function name should be displayFormattedLangText() (with the first letter being lowercase). I think that since all modders would have access to these functions, it's very important that the naming format of functions is the same, even if that doesn't match the individual codder's preferences.
For example, if we had most functions in the format camelCaseIsCool, but then someone makes a new function slightly different like FirstLetterCapitalized, and then maybe someone else would even get to the point of which we have i_prefer_underscores... It just gets a horrible mess for modders, who often would memorize function names based on the content only, not the casing.
