Have the same problem. Not only Chinese characters in comments cause the highlight misposition, but any non-latin symbols!
To reproduce just try to paste into comments 'абвгд'
There is a problem with errors highlighting too. And when have a lot of such comments debugging is very awful.

Prisma version 4.7.1

Yep, can confirm! Seems to be something about how we handle utf-16 vs utf-8 characters and the conversion between how we represent Positions here vs in Engines

Running on: Prisma v4.7.1, VSCode: v1.74.0

Schema for ref

generator client {
  provider        = "prisma-client-js"
}

datasource db {
  provider = "mysql"
  url      = env("DATABASE_URL")
  relationMode = "prisma"
}

model User {
  id Int @id @default(autoincrement())
  email String @unique
  posts Post[]
}

/// абвгд
model Post {
  id Int @id @default(autoincrement())
  author User @relation(fields: [authorId], references: [id])
  authorId Int
}

Can anyone says when this would be done? Is there any plan to close this issue?

Can anyone says when this would be done?

No.

Is there any plan to close this issue?

Yes, when there is capacity. PRs welcome as well, happy to review.

This also breaks quick fix, for example: quick fix of automatically add @@Index will insert into the wrong line.
