I want to know the answer to the following question:
What are MES-1, MES-2, AND MES-3A AND MES-3B part of?
All the background I'm provided with is that "Other standardized subsets of Unicode include the Multilingual European Subsets: MES-1 (Latin scripts only, 335 characters), MES-2 (Latin, Greek and Cyrillic 1062 characters) and MES-3A & MES-3B (two larger subsets, not shown here).". Is that enough to answer the question?
Answer: yes
