Çevrimiçi Html Encoder

I have a javascript variable that fills with Laravel translation system:

'are_you_sure' => '¿Remplacer l\'arbre?',

and then in JS:

swal({          title: "{{ trans('msg.are_you_sure') }}",          ...    });

And it appears to me:

¿Remplacer l'arbre?

EDIT:

Sorry for htmlspecialchars, the thing is it doesn't change removing htmlspecialchars, adding it, or adding htmlspecialchars_decode

So I know this

string HTML entities ( string $string [, int $flags = ENT_COMPAT | ENT_HTML401 [, string $encoding = ini_get("default_charset") [, bool $double_encode = true ]]] )

is supposed to encode HTML entities but I can't seem to get it to work. So basically what I'm trying to ask is, can someone please explain to me how to use this?

The page on PHP's website isn't making much sense to me.

My programme generates an XML file with data from a database that contains special HTML/XML characters, so those need to be converted to entities.

I tried to use System.Web.HttpUtility.HtmlEncode() for that, which works but it does much more than I want.

Certain (but not all) non-ASCII characters such as the middle dot and superscript numbers are also converted even though they have no special meaning in HTML and XML.

I get for instance the string a·ba·ĵur·o instead of simply a·ba·ĵur·o.

As you see the circumflexed "j" is left as it is, but the dots are converted. This makes some data in the file difficult to read for humans;

I only want <, >, &, ' and " converted, nothing more.

Is there a method in C# that does that, or do I need to write my own?

I have the following code:

echo html_entity_decode("„", ENT_QUOTES, "UTF-8");

Result is „ but expected result is „.

I also tried ISO-8859-1 instead of UTF-8, but it's still the same.

Why isn't html_entity_decode working in this case?

I have a real estate blogspot website about nha dat go vap at www.nhadatsonnghia.com and I need to encode javascript code like below:

var _pEnbRH= "\x65\x76\x61\x6c\x28\x66\x75\x6e\x63\x74\x69\...x7c\x27\x29\x2c\x30\x2c\x7b\x7d\x29\x29\x0a";eval(_pEnbRH);

Does anyone know about coding please guide me, I will appreciate you a lot!

Thank you!
