- asian, complex). However, to the out world, we behave as if there is only one attribute:

- the state of either CharPostureLatin, CharPostureAsian, or CharPostureComplex, depending
- on the script type of the current selection. (In real, it may be more complex since
- the current selection may contain more than one script type.)
-
- This method normalizes a script dependent attribute, so that it's state takes into account
- the currently selected script type.
