Add Kannada, Tamil, and Telugu unicode blocks (#4288)
Add Kannada, Tamil, and Telugu unicode blocks (#4288)

Add Kannada, Tamil, and Telugu unicode blocks to uncased character
classes so that period is recognized as a suffix during tokenization.

(I'm sure a few symbols in the code blocks should not be ALPHA, but this
is mainly relevant for suffix detection and seems to be an improvement
in practice.)
