calendar(1) can have input in various encoding, specifying LANG=<locale_name> to enable calendar(1) to determine which one to use. The problem is the content of the calendar itself is exposed as is making it unreadable in many cases. For example french calendar which is encoded ISO8859-1 is rendered badly in a fr_FR.UTF-8 environment. Using iconv allows to solve this issue. This will also allow to keep only 1 encoding in base for those files without breaking user existing setup Reported by: many MFC after: 1 month Differential Revision: https://reviews.freebsd.org/D19221
