What is the only supported character set for file formats such as JSON and Avro?

1. UTF-16

2. ASCII

3. UTF-32

4. UTF-8

The correct answer is: UTF-8

The only supported character set for file formats such as JSON and Avro is UTF-8. This character encoding is widely used and is designed to handle a large range of characters from multiple languages, making it very flexible for representing text data. JSON, as a text-based data interchange format, specifies UTF-8 as its encoding standard, which ensures compatibility and consistency across platforms and applications. Similarly, Avro, a framework for data serialization, also supports UTF-8 encoding to maintain efficiency and interoperability when exchanging data between different systems. The importance of UTF-8 lies in its ability to encode characters from virtually every writing system, which is crucial for modern applications that deal with internationalization and diverse datasets. This makes UTF-8 the preferred choice for these file formats, as it balances performance and broader character representation. Other character sets mentioned may not provide the same level of support and versatility, which is why they are not applicable in this context.
