How to type the prime ( ' ) symbol in a string?

Question

What is the proper syntax to display 25' as output description?

Example:

var sizeData = [            
    {description:'Recommended sizes listed below', value:'', text:'Select Size'},                   
    {description:'Boat < 25 &prime;, value:'size0', text:'Size 0'},
    {description:'25-35 Foot Boat', value:'size2', text:'Size 2'},
    {description:'40-45 Foot Boat', value:'size3', text:'Size 3'},
];

The prime character is a distinct Unicode character. You can use it inside a singe-quote encapsulated string normally. — Šime Vidas, Jan 17 '13 at 01:12

In a JSON file, where all strings are delimited with double quotes, you can just write apostrophes.

In a JavaScript object literal, where you can delimit strings with apostrophes as well, you then will need to escape them with a backslash: '\'' (dobule quote delimiters: just "'").

The prime symbol - which is different from the apostrophe you typed - can be inserted without harm. Depending on the encoding of your file, you might need to write it a bit different. In HTML you can replace it with the entity ′, in both JSON and JavaScript you can replace it with the escape sequence \u2032 if you do not want to use the recommended UTF-8 character ′.

To be clear, escaping is needed *if* you chose to use the single-quotes for that value... if using the double quotes there is no need for escaping the single quote within. – Lawrence Dol Jan 17 '13 at 01:16
It should be noted that in JSON the keys should be enclosed in double quotes too. – bfavaretto Jan 17 '13 at 01:18
@bfavaretto: Since in JSON keys *are* strings, the same rules apply to them – Bergi Jan 17 '13 at 01:24

Like so:

foo: '25′'

Notice that the prime character and the apostrophe character are two different Unicode characters. You can put the prime character inside a single-quote encapsulated string normally.

Btw, above the prime character is printed in monospace font. This is how it looks in sans-serif:

25′, and 25′′

var sizeData = [
{description:\'Recommended sizes listed below\', value:\'\', text:\'Select Size\'},
{description:\'Boat < 25 ′, value:\'size0\', text:\'Size 0\'} ];

You can enclose a (') using a "". Basically like this " ' ".
