+lv (pager, grep, and iconv replacement)
+
+lv is a powerful file viewer like less. lv can decode and encode
+multilingual streams in many encodings, including ISO-8859, ISO-2022,
+EUC, SJIS, Big5, HZ, and Unicode. It recognizes multi-byte patterns
+in regular expressions, and can be run as "lgrep" to act as a grep
+replacement. In addition, lv can recognize ANSI escape sequences for
+text decoration (making it suitable for use as MANPAGER).
+
+lv can also be used as a replacement for iconv(1), by redirecting
+its standard output and using the -I and -O options to set the input
+and output encodings. Although it doesn't support all the features of
+iconv, lv will autodetect the input encoding (which iconv won't).
+
+lv also has one (possibly) unique feature: It can autodetect and
+convert or display multiple character encodings *within the same
+document*.
