Strange characters at the end of big json files

[x011]

This happens at the end of big (24MB) json files:

Any idea why?

Wow. Can't say I'm often editing >10M files with highlighting but I routinely work with >100M files (no highlighting) and I haven't seen any glitches like that.

Try two things:

1. Get SciTE (the text editor from Scintilla, the highlighting backend Notepad2 is using) and try opening your JSON file there. How does it look like?
2. Upload your JSON file here (as zip please), we'll check on our side.

Hi again, 1 - json looks normal on SciTE 4.3.3 and on the original notepad2 2 - I cannot upload the file because it contains sensitive information, like emails and passwords.

I've removed most of the extra options and changed the font, but it didn't solve the problem:

Perhaps this is caused by Scintilla upgrade. Try these two versions:

• very old one from 2016 where we're using the same Scintilla as Notepad2 - https://github.com/ProgerXP/Notepad2e/blob/8b441204fdf33f7379d5ba26af4888f831d321f1/bin/Notepad2.exe
• a later one where we have upgraded it to 3.6.6 (current version is 3.11.2) - R47 from https://github.com/ProgerXP/Notepad2e/releases

Does it make any difference?

@cshnik Any idea how to debug it?

All versions I've tried show the same behaviour:

• Notepad2e-R47-3.6.6.exe
• Notepad2-8b44120-pre3.6.6.exe
• Notepad2e-R148-78f910e-x86.exe
• Notepad2e-R134-ac4b27c-x86.exe

After removing all sensitive data, I end up with an invalid json file, but I still get the same awkward characters. Please notice this happens only at the end of a 25MB file with a single line.
It seems a memory issue, but I'm definitely not an expert, also, it's just a visual artifact because the data is clean on copy paste.
