Trying to find the perfect video snippet title without any special characters. Accessing the API:
https://www.googleapis.com/youtube/v3/searchalong with specifying snippet.
The current output for snippet.title is as follows:
I'M GONNA CARRY HER!!! Fortnite With Karina!
Expected title should be:
I'm gonna carry her!!! Fortnite With Karina!
Initially, it is important to recognize that the data received from the API does not consist of (quote from you) special characters.
Strictly speaking, those strings of characters are referred to as HTML character references, commonly known as HTML entities.
The issue you have come across is a well-documented problem with the API, and unfortunately, there doesn't seem to be any other solution available aside from manually substituting those HTML entities for their corresponding characters.
My recommendation is to avoid a makeshift fix; instead, I suggest utilizing reputable, thoroughly tested libraries that offer reliable solutions based on adherence to the current HTML standards.
In my view, the library developed by Mathias Bynens aligns perfectly with the criteria mentioned above:
he
he (standing for “HTML entities”) serves as a reliable HTML entity encoder/decoder implemented in JavaScript. It encompasses all standardized named character references specified by HTML, effectively manages ambiguous ampersands and various edge cases similarly to how a browser would handle them, boasts a comprehensive test suite, and — notably unlike many other JavaScript solutions — can accurately deal with astral Unicode symbols. Online demo available for testing purposes.
I have found a useful tool called escape-goat that can function either as a standalone function or as a tagged template literal, depending on the specific use case:
const {htmlUnescape} = require('escape-goat');
htmlUnescape("I'M GONNA CARRY HER!!! Fortnite With Karina!");
//=> 'I'm gonna carry her!!! Fortnite With Karina!'
htmlUnescape`Title: ${"I'M GONNA CARRY HER!!! Fortnite With Karina!"}`;
//=> 'Title: I'm gonna carry her!!! Fortnite With Karina!'
It is important to exercise caution when handling html encode/decode operations to prevent any potential risks of XSS exploitation.
If you're looking to avoid importing a library and just stick with raw JS, I stumbled upon a method during my coding journey that might suit your needs for the specific scenario you described. Essentially, this technique involves removing separators in order to access the integer representing a Unicode-16 character. Using fromCharCode, you can look up this integer and retrieve the corresponding character.
const unescape = (str) => {
return str.replace(/&#(\d+);/g, (match, dec) => String.fromCharCode(dec))
}
Just like Matt Hosch pointed out in his response, it's crucial to sanitize any incoming data to steer clear of cross-site scripting vulnerabilities.
