The problem is when i create new post and leave path blank autogenerated from title
I see problem for slugify for latin language not full support
here is example code in current helper (src/utils/helpers.js)
const slugify = string => {
if (!string) return '';
const a = 'àáäâèéëêìíïîıòóöôùúüûñçşßÿœæŕśńṕẃǵğǹḿǘẍźḧ·/_,:;';
const b = 'aaaaeeeeiiiiioooouuuuncssyoarsnpwggnmuxzh------';
const p = new RegExp(a.split('').join('|'), 'g');
return string
.toString()
.toLowerCase()
.replace(/\s+/g, '-') // Replace spaces with -
.replace(p, c => b.charAt(a.indexOf(c))) // Replace special chars
.replace(/&/g, '-') // Replace & with 'and'
.replace(/[^\w-]+/g, '') // Remove all non-word chars
.replace(/-+/g, '-') // Replace multiple - with single -
.replace(/^-+/, '') // Trim - from start of text
.replace(/-+$/, ''); // Trim - from end of text
};
Test
console.log(slugify('Trump gây bàn tán vì ngồi bàn họp nhỏ bất thường'));
The result
trump-gay-ban-tan-vi-ngi-ban-hp-nh-bt-thng
This not correct because missing some charatec
So i have create a contribute i hope the team can merge this
New slugify
const slugify = (str) => {
str = String(str).toString();
str = str.replace(/^\s+|\s+$/g, ""); // trim
str = str.toLowerCase();
// remove accents, swap ñ for n, etc
const swaps = {
