 Well, as unexpected as it is, the answer is yes.
 mount_msdosfs uses libkiconv(3) which dlopen()s libiconv.so, which is not provided
 by the base system and thus has to come from a thirdparty, typically the iconv port.
 We already have a BSD-licensed iconv in the src tree, but it is not connected to
 the build yet.

 That -L controls how the OS internally represents the file names on the filesystem.

 Locale controls output and input of characters.
