Hi Daniel, After merge to trunk, file on disk has proper name: "file With Space.txt". Moreover after commit, file on my disk still has proper name, but when I Checkout to other directory it will have name 'file%20With%20Space.txt'.
Log after second commit says exactly what was happened: A /trunk/file%20With%20Space.txt (from /branches/1.0/file With Space.txt:3) File in trunk was created from file in branch, but the filename was changed. This is unwanted behavior. Bartosz
