Subject: Issue #1407 - skip unused ISO 8859 control codes.
X-Git-Tag: v3.5~250
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8a48fe8214df98fc7cd7f23fb210971921d6282c;p=thirdparty%2Ftvheadend.git

Issue #1407 - skip unused ISO 8859 control codes.

This had the effect of placing unwanted spaces into various channel
names where the broadcaster was sending these control chars.

Thanks to Rene Herbrich for diagnosing this.
