Case Insensitive String Search in Go

When searching through files, it can be crucial to consider scenarios where the string being sought may be encountered with different character casing.

Question: How do I perform a case-insensitive search in a file using Go?

Example:

Searching for the string "Update" should identify and count instances of "update" as a match.

Answer:

To enable case-insensitive string comparisons, Go provides the strings.EqualFold() function. It offers Unicode-aware comparisons, assuring accurate results regardless of the characters' casing. For detailed information, refer to the official documentation: http://golang.org/pkg/strings/#EqualFold.

The following code illustrates its usage:

This script demonstrates that "HELLO" and "hello" are considered equal, as well as the Unicode strings "ÑOÑO" and "ñoño."
