Understanding M3U and M3U8: What is the Difference?

If you have configured an IPTV app, you have definitely seen the terms M3U and M3U8. Although they look identical, there are technical differences in how character encoding and playlist rendering are handled. Here is the explanation.

What is M3U?

M3U stands for MP3 URL. It was originally created in the late 1990s to create play queues for MP3 music files. Over time, it was adapted to hold video paths. An M3U file is written in basic plain text.

What is M3U8?

M3U8 is the Unicode version of the M3U file. It uses UTF-8 character encoding, which allows it to correctly render foreign characters, non-English letters, and emojis in channel names and category titles without corrupting the file.
