Failure to recognize some format and extract values in sscanf

[mortezafs]

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|-|_|)|(
)
