Pattern: Inconsistent text encoding identifier case

Issue: -

Description

Text encoding identifiers should use consistent lowercase format (utf8, ascii) for better readability and convention adherence. The ECMAScript specification doesn't define case sensitivity for these identifiers, but lowercase is the common practice.

Examples

Example of incorrect code:

await fs.readFile(file, "UTF-8");
await fs.readFile(file, "ASCII");
const string = buffer.toString("utf-8");

Example of correct code:

await fs.readFile(file, "utf8");
await fs.readFile(file, "ascii");
const string = buffer.toString("utf8");
