Because the old behaviour is not "buggy".

It simply did not support Unicode, and does the next best thing, 
in casu: it transforms to the system codepage.

A car without ABS and SAT-Nav is not buggy. 
It just doesn't support features which are nowadays called standard.
You can perfectly drive it.

Just as Unicode is nowadays standard, N years ago, it was not.

Since backwards compatibility is very important, we must offer the option.
