Re: TDiff with unicode files without BOM

The problem arises only if the files come without BOM.
Files in UTF-16 with BOM are perfectly OK.

Unfortunately I have an application that produces files without BOM and
I need to put those in svn.

I attach four small files to demonstrate this issue.

File1BOM.txt is a normal UTF-16LE file with BOM
File1NoBOM.txt is the very same file without BOM
Same is for File2

If you start TortoiseMerge File1BOM File2BOM
everything looks ok, but if you use the other two
TortoiseMerge File1NoBOM File2NoBOM
you'll see the problem

Regards.
Mau.
