javascript - Escape HTML tags. Any isue possible with charset encoding? -

-

i have function escape html tags, able insert text html. similar : can escape html special chars in javascript?

i know javascript use unicode internally, html pages may encoded in different charsets utf-8 or iso8859-1, etc..

my question is: there issue simple conversion? or should take consideration page charset?

if yes, idea of way handle that?

ps: example, equivalente php function (http://php.net/manual/en/function.htmlspecialchars.php) has parameter select charset.

no, javascript lives in unicode world encoding issues invisible it. escapehtml in linked question fine.

the place can think of javascript gets see bytes data: urls (typically hidden beneath base64). this:

 var markup = '<p>hello, '+escapehtml(user_supplied_data);  var url = 'data:text/html;base64,'+btoa(markup);  iframe.src = url;

is in principle bad thing. although don't know of browsers guess utf-7 in situation, charset=... parameter should supplied ensure browser uses appropriate encoding data. (btoa uses iso-8859-1, it's worth.)
