How Can I Convert Unicode Escape Sequences in HTML Tags to HTML Entities in Golang?

Conversion of Escape Characters in HTML Tags in Golang

In cases where direct conversion of Unicode escape sequences like "u003chtmlu003e" to its HTML entity equivalent "

Implementation

To achieve this conversion, follow these steps:

• Surround the escaped Unicode sequence with double quotes using the backtick (`) to indicate a raw string literal. This prevents the compiler from interpreting and unquoting the sequence.
• Use strconv.Unquote() to unescape the sequence.

Example

Consider the following code:

// Important to use backtick ` (raw string literal)
// else the compiler will unquote it (interpreted string literal)!

s := `\u003chtml\u003e`
fmt.Println(s)
s2, err := strconv.Unquote(`"` + s + `"`)
if err != nil {
    panic(err)
}
fmt.Println(s2)

Output:

\u003chtml\u003e

Note:
For comprehensive HTML text escaping and unescaping operations, consider using the html package, specifically html.UnescapeString(), although it has limitations in decoding certain Unicode sequences.
Raw string literals (using backticks) are essential to preserve the literal form of the Unicode escape sequence to allow proper unescaping.
