Editing ISO 9660 (section)

=== Romeo ===

''Romeo'' was developed by [[Adaptec]] and allows the use of long filenames up to 128 characters, written directly into the primary volume descriptor using the current [[code page]]. This format is built around the workings of Windows 9x and [[Windows NT]] "CDFS" drivers.<ref name="Romeo">{{cite web|url=http://support.apple.com/kb/TA21734?viewlocale=en_US|title=CD-ROM Discs: Joliet & Romeo Name Definitions|publisher=Apple Inc.|date=1 June 2007|access-date=2010-07-20}}</ref> When a Windows installation of a different language opens a ''Romeo'' disk, the lack of code page indication will cause non-ASCII characters in file names to become [[Mojibake]]. For example, "ü" may become "³". A different OS may encounter a similar problem or refuse to recognize these noncompliant names outright.

The same code page problem technically exists in standard ISO 9660, which allows open interpretation of the supplemental and enhanced volume descriptors to any character encoding subject to agreement. However, the primary volume descriptor is guaranteed to be a small subset of ASCII.
