Lao language support

[qdequele]

Consider MeiliSearch support the Lao language. It seems that the word segmentation is not good and on the _matchesInfo the length of the words is not good (3 chars instead of 1 char).

How to reproduce

Data to insert:

[
  {
    "id": 1,
    "price": "3000000",
    "title": "ເຄື່ອງ ວັດ ແທກ ອຸນຫະພູມ",
    "location": "vientiane"
  },
  {
  "id": 2,
   "title": "Kingston SDCard 64GB + ພ້ອມສົ່ງ ອຸນຫະພູມ",
    "price": "100000",
    "location": "pakse"
  }
]

Search Query:
http://127.0.0.1:7700/indexes/shop/search?q=%E0%BA%AD%E0%BA%B8%E0%BA%99&matches=true&attributesToHighlight=*&filters=location:pakse
