Hello, thank you for responding promptly.
1. wc counts 2 lines in file c, but if you just delete the Њ character, it will count 1 line. Does it mean that wc counts Њ as a LF?
2. Could you recommend a script for pre-processing the corpora?
3. If I run pialign using corpora a and b, I get ailgn.1.pt
which is not what is expected. You will find the files in the attachment.
