I have had some issues with adding in chapters, I will lump them here, I notice no github issues in past cover people's experiences, I presume you could be ignorant.

1. Yes you have to escape some characters (#;), but I attempted adding some and they were omitted even with escaping. Here is a sampling of my disappointments: …’“”/¹²³¼½¾§ (quotes are the slanted types) some seem to be rather elementary (not needing Unicode). The player should be able to show it.
2. I notice limit is 128 long. If this cannot be expanded, perhaps you can look at the bug on the 128th character, though I was using MPC-HC 2013, when you add the last character extra symbols are displayed, I think they differ between files, but are same between chapters. Added characters can be Asian. Maybe a bug in player?
3. The 128 character limit may be reduced to a smaller limit with many(60+) chapters but I couldn't be bothered exploring this, that was for a 339mb audio that is super long. I can submit what I did if you must have it, extract and extend whats there already.
4. I thought I had troubles updating when I tried to use one I applied chapters already, so give that a go if you attempt the above.
5. To save on lines can you allow a global timebase entry. I omit since not convenient as is.

Here is some stuff to get you going. Command:
"C:\Program Files\GPAC\ffmpeg" -i infile -i D:\ADD.txt -map_metadata 1 -codec copy outfile

My generator is a spreadsheet (I paste delimited data from elsewhere), I use Npp to convert tabs to carriage returns. Title length is capped here at a low figure because limit seemed to be less. Material to paste at A3:
`[CHAPTER]	="START="&M3	="END="&M4-1	=LEFT("TITLE="&G3,98)	x	x	Title	x	x	x	x	x	=N3*1000000000	=Q3+P3*60+O3*60*60	0	0	0` GitHub not showing tabs x is blank cell. copy first four columns to Npp.
