Looking forward for solution. https://www.acesetm.biz/ Previous Comments: ------------------------------------------------------------------------ [2020-02-03 06:05:10] requinix@php.net I suppose it could use another small update. ------------------------------------------------------------------------ [2020-02-03 05:27:21] info at ioweb dot gr No problem. I just saw that the title of the bug changed and it's about padded strings while it's failing for all base64 strings. A bit misleading ------------------------------------------------------------------------ [2020-02-03 05:18:05] requinix@php.net @info: Yes, I was wrong about the nature of the bug, and the code I checked my response with also happened to be wrong (and in a way that made it look like mb_check_encoding was working). You can disregard most of what I said :( ------------------------------------------------------------------------ [2020-02-03 05:15:38] info at ioweb dot gr I'd like to mention that For word "δοκιμή" the encoded string is zrTOv866zrnOvM6u and the result is false as well. It's not the padded = signs only. ------------------------------------------------------------------------ [2020-02-02 22:50:06] requinix@php.net Ah shoot, you're right. It's mb_detect_encoding that works on partial strings, not mb_check_encoding. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
