String.sub returns � instead of Ñ

Help and Feedback Scripting Support
#1

Hello, I am currently writing a script which auto generates 3d text using meshes of every letter. This includes letters like ñ, í or è. I loop through the text i want to put in 3d using something like this:

text = 'Héllo'
for i=1,#text do
		game.ServerStorage.Letters['Letter_'..string.sub(text,i,i)]:Clone()
end

However, when the string passes through string.sub, it returns a �(question mark thingy) instead of the letter é, which results in getting Letter_� instead of Letter_é and my script not finding the letter. How do i fix this?

Probably because the character isn’t recognised by either the function or by Roblox itself, so it’s replaced with a question mark.

Here’s some more info:

Yeah i know, but how do i fix this. Like is there another way to get one letter out of a string of text

Avoid attempting to find non-alphanumeric text.

I cant, because I want this to be dynamic with every letter. That way i can translate 3d texts for other languages

Because "é" is counted as two characters in string encoded in UTF-8, C9 A9.

In that case, you can use utf8.sub in lieu of string.sub

Here’s an implementation of utf8.sub from Lua unicode, using string.sub() with two-byted chars - Stack Overflow

function utf8.sub(s,i,j)
    i=utf8.offset(s,i)
    j=utf8.offset(s,j+1)-1
    return string.sub(s,i,j)
end

Though you can’t modify the content of the utf8 table, you might want to rename the function.

You could use gsub(), and attempt to replace the string with a recognisable string like “ewithaccent” and then perform the sub() function on that new string looking for “ewithaccent” instead.

But it doesn’t have utf8.sub though.

I recognise that, that’s why I deleted the post immediately - don’t know if that showed up though. That’s my bad because I didn’t check which methods were ported over.
