Issue #483: these circled-letter suffixes are in-list markers for
human readers (subscription-required, geo-blocked, YouTube-sourced,
etc.), but were leaking into the generated tvg-name verbatim (e.g.
tvg-name="Rai 1 Ⓖ"), breaking EPG matching for any provider keying
off channel name. Now stripped from tvg-name only; the display name
after the comma still shows the marker as before.
The 212.79.122.11:5014 UDP-relay server (1+1 Ukraina, Inter, 2+2, M1,
Mega, K1, Enter-Film, TET, ДІМ) refuses connections now. Fixed 9
channels with working sources (mostly stream.mcquack.net / antik.sk).
6 more on the same dead server (Bigudi, Novyi Kanal, ПлюсПлюс,
Ми — Україна, Оце ТБ, Піксель TV) had no replacement found - marked
Invalid. Also fixed/cleaned up entries on a separate dead
nashnet.tv/ott.blue/tvstitch.com cluster. Partial progress on #986.
Spain: Televisión Melilla's domain no longer resolves, marked
Invalid (#1012 - no working replacement found for it or Rioja TV).
Add ISO 3166-1 alpha-2 country codes via tvg-country attribute
to all #EXTINF lines, enabling IPTV players to filter and display
channels by country.
