Javascript：在svg中使用字体图标。 <i>How do I use “\\u”?\u003c/i> 如何使用“ \\ u”？

Question

I am using font icons generated by icomoon.com and displaying them as svg text using Raphael .

Basically, I have icons like these:





%

I have been inserting them into my code like so:

paper.text(x, y, iconString).attr({
   'text-anchor': 'end', 
   'font-family':'myFont', 
   'font-size':12})

BUT, in order for me to get this to work, I've had to use the Javascript way to show icons, but I don't really know enough about it to know what I'm doing wrong. For example:

iconString = "\ue005"; //This is for icon "". Works!
iconString = "\uf331"; //This is for icon "". Works!
iconString = "\ue0c1"; //This is for icon "". Works!
iconString = "\uf003"; //This is for icon "". Works!
iconString = "\u25"; //This is for icon "%". DOES NOT WORK!

So I've just been replacing "&#x" with "\\u\u0026quot; and it has been working... but not when it is short. :/ How do I do this?

I've also used the whole string (like "" , but that has only been working in text and not svg for me.)

Any ideas? Thanks!

Answer 1

\\u\u003c/code> requires four digits.

iconString = "\u0025";

Alternatively, two-digit numbers can also be done like so:

iconString = "\x25";

Alternatively alternatively, you can just use the plain character:

iconString = "%";
