Is there a way to enter a non-space "invisible" letter in Windows?

Gmail lets you have hierarchy in tags. In other words, you can nest tags.

But, in displaying nested tags in the left-panel, Gmail only indents nested tags down to the second level. From the third level and down, the tags are indented the same, making it impossible to discern the hierarchy based on the indentation.

I've been trying different things to overcome this, to no avail.

My last hope is to insert a non-space, "invisible" character that will create the illusion of an indentation. (i.e., one "invisible" character in front of the third level, two such invisible characters in front of the fourth level, etc.)

Is this possible?

There is such a thing as a “No-Break Space” and as Wikipedia explains it:

In word processing and digital typesetting, a non-breaking space (" "), also known as a no-break space or non-breakable space (NBSP), is a variant of the space character that prevents an automatic line break (line wrap) at its position.

And according to that Wikipedia entry it can be manually entered as Unicode by doing this key combo:

alt+0+1+6+0

More general info on manually entering Unicode characters in Windows can be found here.
