# M3U to Samsung SMPL Playlist Converter
# Written by ChatGPT

# This script converts an M3U playlist file to the Samsung SMPL format. It reads an M3U file, extracts file paths,
# and generates a Samsung SMPL JSON file with a "members" array, where each item represents a file from the M3U playlist.
# Samsung SMPL format is old but used in the samsung music app here: https://github.com/AyraHikari/SamsungMusicPort

When running the file, it showed a UnicodeDecodeError on my device
UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 250: character maps to <undefined>

This error can be rectified by adding the encoding when opening the file

with open(m3u_file, "r") as m3u:
to
with open(m3u_file, "r", encoding="utf8") as m3u:

worked beautifully otherwise, thanks a lot for this.
