Re: [algogeeks] How to read multiple utf-8 encoded string from stdin
this way only helps in linux but when i use in windows with utf-8 encoded input file for reading characters i cant do it , secondly how to count non ascii characters from utf-8 string , any one is having any idea on this ?

fgets() can decode UTF-8 encoded files if you use Visual Studio 2005 and
up. Change your code like this:
infile = fopen(inname, r, ccs=UTF-8);

Re: [algogeeks] How to read multiple utf-8 encoded string from stdin
The Code is Awsome pradeep except few things :
1) the output is coming wrong in 2 cases : a) x√ab c counting non-ascii as
2 it should be 1
b)ɖ Ɛ
counting non-ascii as 4 it should be 2.

Re: [algogeeks] How to read multiple utf-8 encoded string from stdin
How about counting non ASCII from it ... Checking mere ASCII doesn't help as utf8 it self is combination of characters ...
