Typescript: Special characters in 'enum' type will be compiled to unicode by default

[yeze322]

TypeScript Version: 2.9.1

Search Terms: typescript unicode, typescript enum unicode

Code

export const TestObject = {
  WELCOME: '你好',
  TEST: 'тест',
}

export enum TestEnum {
  WELCOME = '你好',
  TEST = 'тест',
}

Expected behavior:
Fields in TestObject and TestEnum ought to be compiled to a consistent encoding format (utf8).

Actual behavior:
Special characters in Object were compiled to utf8 while those in Enum were compiled to unicode.

In JSX same problem

I think Typescript should have cli parameter to keep non Latin characters as is (and may be TRUE by default)
