Mailto Special Characters

Special Character when using the mailto: option

It's all about encoding.

£ is character number 0xA3. This, when encoded "properly" (ie. in UTF-8), is converted to 0xC2A3 - coincidentally, you have the same A3 in there, which means the rendered result, £, looks like it just acquired a "random"  out of nowhere.

Solution: Encode the £ properly. Try £ first, and if that doesn't work try %A3.

Html hyperlink body option in mailto does not support some special characters like '&'

You need to encode the entire url value after Subject= with encodeURIComponent.

If the subject contains HTML and/or urls themselves, then those also need to be encoded using encodeURI. Yes, this means 2 layers of encodeURIComponent for some parts.

const myLink = "http://localhost:5500/abc/def.html?did=" + value + "&title=" + encodeURIComponent(titlevar);
const body = encodeURIComponent('Click here to view my example: ' + myLink);
const emailstring = `mailto:?Subject=Sometext&body=${body}`;

The general issue is that you should always encode your strings when you are embedding them in a url. If that encoded string is embedded in another url, encode that too.

Passing special characters to mailto body blows up JavaScript

Mailto is a URI scheme so all of its components must be URI encoded. You can use JavaScript encodeURIComponent function to encode mailto components. Please see the following example:

function buildMailTo(address, subject, body) {
    var strMail = 'mailto:' + encodeURIComponent(address)
                   + '?subject=' + encodeURIComponent(subject)
                   + '&body=' + encodeURIComponent(body);
    return strMail;
}
var strTest = buildMailTo('abc@xyz.com', 'Foo&foo', 'Bar\nBar');
/* strTest should be "mailto:abc%40xyz.com?subject=Foo%26foo&body=Bar%0ABar" */
window.open(strTest);

Hope this help.

HTML mailto subject with '&'

You need to URL-encode the text; so it becomes:

<a href="mailto:no-one@snai1mai1.com?subject=free chocolate %26 cake&Body=get free hurry.">example
</a>

%26 is the Url-encoded representation of &

Mailto body, special characters?

have you tryed encoding the values with javascript?

eg

<a href="demo@email.com?subject='+encodeURI('emailSubject')+'&body='+encodeURI('emailBody')+'">

Set a mailto link with a subject containing an ampersand (&)

In order to get special/reserved characters into a URL, you must encode them - to get an & to work, it must be encoded to %26.
