For backup software, I usually make a program or script to make all 64k (minus a few) combination of two-byte-filenames in a dir, then ask for a backup and later a restore of it. Surprising results when backup programs decide that certain combinations of bytes are "illegal" and won't back them up for you, when they in reality are valid unix file names.
Most of the time I guess they know "Our gui will have a hard time painting the creative chars needed in a certain way". Or just malice. 2015-03-05 11:38 GMT+01:00 Peter N. M.
