Language Support: Windows-make: Reading Files: UTF-16( Unicode ): As your Language: Opposite side, we could find:

Opposite side means flip side:
We could find colon by use of a_compare:
And we can analyze on the level1, which is "tokenizer".
That was step back in my program list but using standard library in C is the most effective, we respect.
We appriciate their work.
