Reproduction steps
- Open any interface that restricts maximum string length.
- Enter any string approaching the maximum character limit, but with some SMP characters. (e.g.
𐑛𐑦𐑕𐑣𐑸𐑥𐑩𐑯𐑦 | 最不調和の伝播者 | 異議の元素, my actual display name at 28 characters) - Hit "apply".
Expected behaviour
String length validation passes (28 ≤ 32).
// Please, use either, I just want this bug to be fixed and get it over with.
"use strict" ;
const isLengthExceeded = function ( input , maxLength ) {
let actualSize = 0 ;
for ( const char of input ) {
actualSize ++ ;
};
return actualSize <= maxLength ;
};
// Alternative method
const isLengthExceeded = function ( input , maxLength ) {
return Array . from ( input ). length <= maxLength ;
}; Actual behaviour
String length validation fails (37 > 32), both in the browser and in the API.
"use strict" ;
const isLengthExceeded = function ( input , maxLength ) {
return input . length <= maxLength ;
