Sorting it all Out Michael Kaplan's random stuff of dubious value Be sure to read the disclaimer here first!
The question asked by someone internally was:
Are East Asian script languages considered to be complex script languages?
Well, I suppose it would depend on both one's definition of "East Asian script languages" and "complex script languages", really.
If I use the Microsoft definition of Complex then I am only thinking of ones that require special handling when rendered by Uniscribe.
And if I use the general Microsoft definition of East Asian to not include South Asian or Southeast Asian, then I cannot say YES on the basis of Thai or Vietnamese.
However, one has to consider:
and then say that the answer is YES unless you plan to rephrase your question. :-)
Usually people asking the question will rephrase at that point, as they were often thinking only on CJK (Chinese/Japanese/Korean) when they asked, but I remind them of old Hangul, which is obviously quite Korean. And even while a Korean colleague noted it wasn't a mainstream scenario, it was also noted to be something even high school kids knew about and knew.
So the answer is still YES unless the question is reframed yet again!
