derick 2025-01-16 10:35 administrator ~0007154	There is way too little information in this report. There is no actual script to test, and I'm certainly not going to "Install Windows 10". It is also not "urgent" or a "crash". Even if you provide an actual full test case, I sincerely doubt there is a bug in Xdebug here; and merely something where you are messing up character sets.

Undralex 2025-01-16 18:35 reporter ~0007155	Unfortunately, there is no way to send a script here. There is no way to request a test in another version of Windows. It's not clear what to do with a broken xdebug. Most likely, this won't work in another OS either.

Undralex 2025-01-17 00:15 reporter ~0007157	It might be clearer this way. Everything worked fine in php 7

Undralex 2025-01-17 00:37 reporter ~0007158	To reproduce this bug, you need to run a simple 4-line script. The question is, how do I pass this script to you?

Undralex 2025-02-01 18:47 reporter ~0007168	Tested PHP 8.3 + xdebug on the Ubuntu operating system var_dump does not output half of the lowercase characters in Windows-1251 encoding

derick 2025-03-09 16:06 administrator ~0007206	Turns out to be a duplicate of 0002318 which is now fixed for Xdebug 3.4.2 (to be released soon).
