<p>The VM works with file names as if they are encoded using UTF-8 (or some other system specific Unicode encoding). This is the default on operating systems that enforce Unicode encoding, i.e. Windows and MacOSX.</p>
- <p>By enabling Unicode file name translation on systems where this is not default, you open up to the possibility that some file names can not be interpreted by the VM and therefore will be returned to the program as raw binaries. The option is therefore considered experimental.</p>

+ <p>The <c>+fnu</c> switch can be followed by <c>w</c>,
+ <c>i</c>, or <c>e</c> to control the way wrongly encoded file
+ names are to be reported. <c>w</c> means that a warning is

+ file name is "skipped" in directory listings, <c>i</c> means
+ that those wrongly encoded file names are silently ignored and
+ <c>e</c> means that the API function will return an error
+ whenever a wrongly encoded file (or directory) name is
+ encountered. <c>w</c> is the default. Note that

+ A bug in the implementation of offline schedulers has
+ been fixed. The bug was introduced in OTP-R16A/ERTS-5.10,
+ and caused work-stealing between schedulers to fail. This
+ in turn, caused work to accumulate in some run-queues.
+ The bug was only triggered when there were offline
+ schedulers in the system, i.e., when the amount of online
+ schedulers was less than the total amount of schedulers.
+ The effect of the bug got more severe the larger amount
+ of offline schedulers the system had.</p>
