Media files with square brackets are removed when opening .pls / .m3u playlist file

Description

Expected behavior

All media files in the .pls / .m3u playlist file should be loaded, as is on VLC Windows.

Actual behavior

Media files with square brackets [] are removed from playlist when opening the .pls / .m3u playlist file.

Steps to reproduce

1. VLC Android is able to play [.mp3 directly.

2. Write a simple .pls playlist file. For example,

[playlist]

File1=/sdcard/[.mp3
Title1=test square bracket
Length1=180000

NumberOfEntries=1
Version=2

3. Open VLC Android. Browse the folder containing the .pls file.
   There should be a number 1 under the filename.
   However, VLC Android would show Empty.

4. Click on the playlist. There would be no respond because VLC thinks it's empty, unopenable.

5. Open playlist on VLC Windows. Music is played successfully.

6. This time, try a.mp3,

[playlist]

File1=/sdcard/a.mp3
Title1=test square bracket
Length1=180000

NumberOfEntries=1
Version=2

7. VLC Android would play this playlist successfully.
