I've tested this within d-i using three testcases: 1. Microsoft Windows XP Homé Edition (ISO-8895-1 encoded) 2. Microsoft Windows XP Homé Edition (UTF-8 encoded) 3. (Microsoft) Windows/XP - Home_Edition 89&90 The 3rd case was chosen to test if any of the characters in it would cause problems. 1: causes the hang described in the bug report 2: is accepted fine by d-i and displayed correctly 3: works fine for both d-i and grub Although UTF-8 encoding seems to work for d-i, I've chosen to sanitize the input as: - we don't really know what encodings boot.ini could be in, so we don't really know what we should convert _from_ if we wanted to convert the input to UTF-8; - I have no idea what grub would make of UTF-8 encoding. I've committed a patch to os-prober that will make d-i fall back to a default description if the one in boot.ini contains any other characters than "a-zA-Z0-9 &()/_-" (chosen somewhat arbitrarily). I've tested that this rejects both 1. and 2. and allows 3. Cheers, FJP
