Is there any difference in this code for removing the first letter from the variable? In this case, emojis.

const editFileName = String.fromCodePoint(interaction.channel.name.codePointAt(0));
const fileName = interaction.channel.name.replace(editFileName, '') + '.txt';

OR

const fileName = interaction.channel.name.substring(2) + '.txt';

Even if an emoji shows as one character it may be made by 2 or more code points.
The first code removes exactly 1 code point. The second removes exactly 2 code points.
The easiest way is to have a separator between the emoji and text (😄 Hello). Here you can split by the space and shift the emoji.
Or use a regex to remove the emoji.

Regex would be easier as Emojis are part of multibytes characters but not all multibytes characters are emojis

basically everything that is not using the same alphabet as english + ASCII Symbols are multibytes sequences (like à; ù in french, 漢, 字 in japanese, 한글 in korean, you get the idea)

If i recall correctly, emojis span over a specifc range of multibyte sequences
