Can I enter special characters from a JSON?


How can I enter special characters within a JSON? For example, if I have:

    "a": "Hola mundo"

and I want to put the word "world" in quotes. Try escaping them and with the HTML code: " The string I show in a web page, but neither of the two options worked, I do not know if the library that loads it or is something inherent in the use of JSON.



Escaped quotes: \"

Do not adequately pose the question. I see that my problem is a thing of the library ngx-translate for Angular2 , not for the JSON itself. This library stores the translations in the JSON file, but it has not allowed me to enter double quotes within them as I indicated before.

According to the standard used by for the use of strings or String , Values should start with a " to use a valid character except double quotes should use the backslash \ and after that the control character that you need obviously ending with "

Some valid JSON

let comillaDoble = {
    "a": "comilla \"doble\""
let comillaSimple = {
    "a": "comilla \'simple\'"
let saltoCarro = {
    "a": "\t tab \n Enter"
let barras = {
    "a": "barra1\\/barra2 \u00F1"


Now what does that \u mean, what's it for? simple is used for special characters call accents and accents among others in unicode format .

miJson = {
"resultado":  "1 es \u003C 2 ", 

An example of when we use Unicode is when we send the answers via GET the parameter is transformed to unicode with the command encodeURIComponent

If you can, you should only use a backslash ( \ ) in front of the quotes, it will not be valid if you do not have opening and closing quotes.


   "a": "Hola \"mundo\""

I leave you with these two solutions:

    "a": "Hola \"mundo\""

Otherwise you can try:

    'a': 'Hola "mundo"'

And if you experience any other problem, use the JSON.parse function, once you have your object correctly stored in your script.

In JSON, as with any other string, there are escape chains that allow the insertion of special characters such as: the line break, the tabulation, the tildes, among others ... And for this particular cas, you must place the backslach followed by the character that you want to take as a string (\ ") ...

    "a": "\"Hola mundo\""
