As no consistency is enforced, the Erlang VM can do no consistent translation of all file names.

The reason "raw file names" is introduced in the system is to be able to consistently represent file names given in different encodings on the same system. Having the VM automatically translate a file name that is not in UTF-8 to a list of Unicode characters might seem practical, but this would open up for both duplicate file names and other inconsistent behavior. Consider a directory containing a file named "bj�rn" in ISO-latin-1, while the Erlang VM is operating in Unicode file name mode (and therefore expecting UTF-8 file naming). The ISO-latin-1 name is not valid UTF-8 and one could be tempted to think that automatic conversion in for example <c>file:list_dir/1</c> is a good idea. But what would happen if we later tried to open the file and have the name as a Unicode list (magically converted from the ISO-latin-1 file name)? The VM will convert the file name given to UTF-8, as this is the encoding expected. Effectively this means trying to open the file named <<"bj�rn"/utf8>>. This file does not exist, and even if it existed it would not be the same file as the one that was listed. We could even create two files named "bj�rn", one named in the UTF-8 encoding and one not. If <c>file:list_dir/1</c> would automatically convert the ISO-latin-1 file name to a list, we would get two identical file names as the result. To avoid this, we need to differentiate between file names being properly encoded according to the Unicode file naming convention (i.e. UTF-8) and file names being invalid under the encoding. This is done by representing invalid encoding as "raw" file names, i.e. as binaries.</p> +<p>The core system of Erlang (kernel and stdlib) accepts raw file names except for loadable drivers and executables invoked using <c>open_port({spawn, ...} ...)</c>. <c>open_port({spawn_executable, ...} ...)</c> however does accept them. As mentioned earlier, the arguments given in the option list to <c>open_port({spawn_executable, ...} ...)</c> undergo the same conversion as the file names, meaning that the executable will be provided with arguments in UTF-8 as well. This translation is avoided consistently with how the file names are treated, by giving the argument as a binary.</p> +<p>To force Unicode file name translation mode on systems where this is not the default is considered experimental in OTP R14B01 due to the raw file names possibly being a new experience to the programmer and that the non core applications of OTP are not tested for compliance with raw file names yet. Unicode file name translation is expected to be default in future releases.</p> +<p>If working with raw file names, one can still conform to the encoding convention of the Erlang VM by using the <c>file:native_name_encoding/0</c> function, which returns either the atom <c>latin1</c> or the atom <c>utf8</c> depending on the file name translation mode. On Linux, a VM started without explicitly stating the file name translation mode will default to <c>latin1</c> as the native file name encoding, why file names on the disk encoded as UTF-8 will be returned as a list of the names interpreted as ISO-latin-1. The "UTF-8 list" is not a practical type for displaying or operating on in Erlang, but it is backward compatible and usable in all functions requiring a file name. On Windows and MacOSX, the default behavior is that of file name translation, why the <c>file:native_name_encoding/0</c> by default returns <c>utf8</c> on those systems (the fact that Windows actually does not use UTF-8 on the file system level can safely be ignored by the Erlang programmer). The default behavior can be changed using the <c>+fnu</c> or <c>+fnl</c> options to the VM, see the <c>erl</c> command manual page.</p> +<p>Even if you are operating without Unicode file naming translation automatically done by the VM, you can access and create files with names in UTF-8 encoding by using raw file names encoded as UTF-8. Enforcing the UTF-8 encoding regardless of the mode the Erlang VM is started in might, in some circumstances be a good idea, as the convention of using UTF-8 file names is spreading.</p> +</section> +<section> +<title>Notes about MacOSX</title> +<p>MacOSXs vfs layer enforces UTF-8 file names in a quite aggressive way. Older versions did this by simply refusing to create non UTF-8 conforming file names, while newer versions replace offending bytes with the sequence "%HH", where HH is the original character in hexadecimal notation. As Unicode translation is enabled by default on MacOSX, the only way to come up against this is to either start the VM with the <c>+fnl</c> flag or to use a raw file name in <c>latin1</c> encoding. In that case, the file can not be opened with the same name as the one used to create this. The problem is by design in newer versions of MacOSX.</p> +<p>MacOSX also reorganizes the names of files so that the representation of accents etc is denormalized, i.e. the character <c>�</c> is represented as the codepoints [111,776], where 111 is the character <c>o</c> and 776 is a special accent character. This type of denormalized Unicode is otherwise very seldom used and Erlang normalizes those file names on retrieval, so that denormalized file names is not passed up to the Erlang application. In Erlang the file name "bj�rn" is retrieved as [98,106,246,114,110], not as [98,106,117,776,114,110], even though the file system might think differently.</p> +</section> +</section> +<section> <title>Unicode-aware modules</title> <p>Most of the modules in Erlang/OTP are of course Unicode-unaware in the sense that they have no notion of Unicode and really shouldn't have.
