Failure to recognize some format and extract values in sscanf

[Morteza Fard Saffari]

Hi.
First of all thank you for your great job.
I'm going to report some bug in sscanf function.
sscanf can not recognize this formats and extract matched values.
Tested at: Windows and ubnutu

Format 1: "%[^[]]"
Test Case:

let dataScanned = sscanf('mobile[country_code]', '%[^[]]');
console.log(dataScanned);

JS sscanf output:
[]
PHP output:

Array
(
    [0] => mobile
)

Format 2: "%[^[][%[^]]]"
Test Case:

let dataScanned = sscanf("alphanumericWithCustomChars[en,fa|-|_|)|(]", "%[^[][%[^]]]");
console.log(dataScanned);

JS sscanf output:
[]
PHP output:

Array
(
    [0] => alphanumericWithCustomChars
    [1] => en,fa|-|_|)|(
)
