Subject: [PATCH] v4l-utils/contrib/gconv: fix conversion errors on ARIB-STD-B24 strings

From: Akihiro Tsukada <tskd08@...il.com>

Some ARIB strings in operation requires that
codepoints from the 'extra symbols' charset fallback to 'kanji'.
Remove the range check for 'extra symbols' to accept those strings.
