Surely certain people did know, but those people weren't in a position to do anything about it.

Specifically, there were surely people who knew that because historical Chinese place names, Japanese nicknames, and so on, were not included in the original "Unicode" (it wasn't called UCS-2 yet) it was insufficient for complete expression of Asian languages.

There were also many people who objected to Han unification, which is a different problem.

But all of these objections were discarded because of the overwhelming mandate for a fixed-width encoding. The original "Unicode" was conceived as a "16-bit" initiative. Its 16-bit-ness was an essential aspect of the design and the Unicode Consortium did what they had to do to fit all scripts and characters "in modern use" into 16 bits.

From the Wikipedia article on Han Unification[1]:

> Some of the controversy stems from the fact that the very decision of performing Han unification was made by the initial Unicode Consortium, which at the time was a consortium of North American companies and organizations (most of them in California), but included no East Asian government representatives. The initial design goal was to create a 16-bit standard, and Han unification was therefore a critical step for avoiding tens of thousands of character duplications.
