Get directory separator char on Windows? (‘\’, ‘/’, etc.)

by

While the ₩ and ¥ characters are shown as directory separator symbols in the respective Korean and Japanese windows versions, they are only how those versions of Windows represent the same Unicode code point U+005c as a glyph. The underlying code point for backslash is still the same across English Windows and the Japanese and Korean windows versions.

Extra confirmation for this can be found on this page: http://msdn.microsoft.com/en-us/library/dd374047(v=vs.85).aspx

Security Considerations for Character Sets in File Names

Windows code page and OEM character sets used on Japanese-language systems contain the Yen symbol (¥) instead of a backslash (\). Thus, the Yen character is a prohibited character for NTFS and FAT file systems. When mapping Unicode to a Japanese-language code page, conversion functions map both backslash (U+005C) and the normal Unicode Yen symbol (U+00A5) to this same character. For security reasons, your applications should not typically allow the character U+00A5 in a Unicode string that might be converted for use as a FAT file name.

Also, I don’t know of any Windows API function that gets you the system’s path separator, but you can rely on it being \ in all circumstances.

The following fundamental rules enable applications to create and process valid names for files and directories, regardless of the file system:

…

Use a backslash (\) to separate the components of a path. The backslash divides the file name from the path to it, and one directory name from another directory name in a path. You cannot use a backslash in the name for the actual file or directory because it is a reserved character that separates the names into components.

About /

Windows should support the use of / as a directory separator in the API functions, though not necessarily in the command prompt (command.com).

Note File I/O functions in the Windows API convert “https://stackoverflow.com/” to “\” as part of converting the name to an NT-style name, except when using the “\?\” prefix as detailed in the following sections.

It’s ‘tough’ to figure out the truth of all this, but this might be a really helpful link about / in Windows paths: http://bytes.com/topic/python/answers/23123-when-did-windows-start-accepting-forward-slash-path-separator
