I want to know the answer to the following question:
How long has Microsoft Windows supported WGL-4?
All the background I'm provided with is that "Several subsets of Unicode are standardized: Microsoft Windows since Windows NT 4.0 supports WGL-4 with 652 characters, which is considered to support all contemporary European languages using the Latin, Greek, or Cyrillic script.". Is that enough to answer the question?
Answer: yes
