JavaScript: Unicode space character

I want to insert the space character into the innerHTML of a DOM element, but the space character must be declare in Unicode syntax.

For example, something like this: ...innerHTML开发者_StackOverflow社区 += '\u83838383';

I am not quite sure what character you are hoping to get with 8383 - not to mention 83838383, but it certainly doesn't seem to be the space character for any encodings I am familiar with. Are you by chance looking for:

• ASCII Space =   = \u0020
• En Space =   = \u2002
• Em Space =   = \u2003
