It doesn't look bad to me but I could go into deeper investigation as I
couldn't type that word using any of the thai layouts from scim. Could
you give us some more hints to type this on scim?

Did you try to type some text in another language (and trigger
autocorrection too) between those two iterations of the steps to see if
your patch didn't alterate anything there?

My last question is how do it come that this language setting alters the
first word but not the second one?
