Malayalam: $$\frac{ക}{ച}$$ Tamil: $$\frac{க}{த}$$ Hindi: $$\frac{क}{च}$$

Simple forms like $$ക$$ also fails!

Another problem:

rendering in MathML.

Given the example of the non standard text character ä (a-Umlaut). It has to be mentioned that
 * $$ä$$ is no valid even though it's rendered in a way that it could be considered as correct.
 * whereas $$\text{ä}$$ or $$\text{\"a}$$ are both valid tex input but the second input is not rendered correctly (it's supposed to look like the first input).
