#### 19.2.2.2 Special Characters in Pathname Components ¶

Strings in pathname component values never contain special characters that represent separation between pathname fields, such as slash in Unix filenames. Whether separator characters are permitted as part of a string in a pathname component is implementation-defined; however, if the implementation does permit it, it must arrange to properly “quote” the character for the file system when constructing a namestring. For example,

     ;; In a TOPS-20 implementation, which uses ^V to quote
     (NAMESTRING (MAKE-PATHNAME :HOST "OZ" :NAME "<TEST>"))
    ⇒  #P"OZ:PS:^V<TEST^V>"
    NOT⇒ #P"OZ:PS:<TEST>"
