Invalid continuation byte

[romafederico]

macOS, Webstorm 2017.1, Reactjs

I'm receving a utf-8 encoded JSON, converting it to a string and then utf8.decode(str).

At some point I'm getting the error Invalid continuation byte. Is there a way in which I can find the byte that is causing this error? This error appears with some of the users of my DB, not all, and I need to compare them.

Thanks

I am having the same issue. I'm trying to convert strings like that:

let test1 = 'Östliche'; // must be "Östliche"
let test2 = 'Neuwiesenstraße'; // must be "Neuwiesenstraße"

console.log(utf8.decode(test1));
console.log(utf8.decode(test2));

// german special characters
let test1 = "Ä"; // Ä fails
let test2 = "ä"; // ä passes
let test3 = "Ãœ"; // Ü fails
let test4 = "ü"; // ü passes
let test5 = "Ö"; // Ö fails
let test6 = "ö"; // ö passes
let test7 = "ß"; // ß fails

// other special characters
let test8 = "Á"; // Á passes
let test9 = "á"; // á passes

All lowercases pass the test all uppercases not, except "ß" there is no lower / uppercase in german. Tested some other special characters but they passed the test.

Similar issue with emojis, anybody has an idea on how to fix it (other than a try / catch cop out?)

Similar issue, circumventing with a try catch block,

error:

this is an example of the input:

Wij de werkgroep “KREKEROCK “ organiseren al een paar jaar tijdens de kerstperiode, omdat deze periode zich ui tstekend leent om eens stil te staan bij al het leed in de wereld, het muziekfestival KREKEROCK.
De opbrengst is steeds integraal voor CADAATAN KORTEMARK.
CADAATAN KORTEMARK houdt zich vooral bezig met het verbeteren van de omstandigheden waarin kinderen in bepaalde schooltjes op de Filip ijnen de lessen volgen. De vereniging is vooral actief in het noorden van het eiland CEBU, meer bepaald in enkele barangay’s van SAN REMIGIO.

Similar issue trying to convert the word "Información". Has anyone fixed this issue? I've been all day trying to solve this but I haven't found the solution :(

[mboughaba]

@AlejaRo

console.log(utf8.encode('Información')); // => Información
console.log(utf8.decode(utf8.encode('Información'))); // => Información

Please show us a snippet I've surrounded it with a try/catch and it seems to work so far

according to the tests, this error is thrown when an invalid sequence is encountered

• 3 bytes instead of 4 bytes
• mix between unicode and hex sequences

+1 Having this issue with the letter "ß" in the string

[sebastianDejoy]

Same here when utf8.decode('账单信息') returning Error: Invalid continuation byte. It should decode to 账单信息 , is the library having issues with code points representated in 3 bytes or more (like chinese and korean)?

I'm receving a utf-8 encoded JSON, converting it to a string and then utf8.decode(str).

as you receive the utf-8 encoded JSON and store it into a string you get the string re-encoded in UCS2

decoding as it's utf8 raises an error as expectesd

@PitPanda1

I am having the same issue. I'm trying to convert strings like that:

let test1 = 'Östliche'; // must be "Östliche"
let test2 = 'Neuwiesenstraße'; // must be "Neuwiesenstraße"

'Östliche' is not UTF-8
