Hi PerlMonks,

Information:
1. A Japanese compressed file(tab separated), Say A having products information (iphone etc), columns: name, description, image, uniqueid, rid1, rid2, url
2. Another file, say B having mid, rid, ntid (column separated).
3. rid1, rid2 => A & rid => B are numerical values.

What I want:
If rid from B matches rid1(from A), get that line form A into third file, Say C. In case, rid is null then rid(from B) to be matched with rid2 (from A). If rid1 & rid2 don't have values, leave that line.
Also I've to add some values to the url (from A) & then it's to be pushed to 3rd file C after rid comparison.

The main problem I've are:
1. How to handle the japanese? Do I have to use any modules? as saving the japanese character to a perl variable turn to junk.
2. There are 30 files like file A, each having 1 million of lines in them. What would be the efficient way to do this in perl?


Help is much appreciated!
