Equivalent to self.to_s.length; see String#length.

Returns clean pathname of self with consecutive slashes and useless dots removed. The filesystem is not accessed.

If consider_symlink is true, then a more conservative algorithm is used to avoid breaking symbolic linkages. This may retain more .. entries than absolutely necessary, but without accessing the filesystem, this can’t be avoided.

See Pathname#realpath.

See FileTest.readable?.

See FileTest.writable?.

Removes a file or directory, using File.unlink if self is a file, or Dir.unlink as necessary.

Returns current codepage.

WIN32OLE.codepage # => WIN32OLE::CP_ACP

Sets current codepage. The WIN32OLE.codepage is initialized according to Encoding.default_internal. If Encoding.default_internal is nil then WIN32OLE.codepage is initialized according to Encoding.default_external.

WIN32OLE.codepage = WIN32OLE::CP_UTF8
WIN32OLE.codepage = 65001

Returns current locale id (lcid). The default locale is WIN32OLE::LOCALE_SYSTEM_DEFAULT.

lcid = WIN32OLE.locale
