I'm looking to prevent a line break after a hyphen -
on a case-by-case basis that is compatible with all browsers.
Example:
I have this text: 3-3/8"
which in HTML is this: 3-3/8”
The problem is that near the end of a line, because of the hyphen, it breaks and wraps to the next line instead of treating it like a full word...
3- 3/8"
I've tried inserting the "zero width no break character", 
with no luck...
3-3/8”
I'm seeing this in Safari and thinking it will be the same in all browsers.
The following is my doctype
and character encoding...
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
Is there any way I can prevent these from line-breaking after the hyphen? I do not need any solution that applies to the whole page... just something I can insert as needed, like a "zero width no break character", except one that works.
Here is a Demo. Simply make the frame narrower until the line breaks at the hyphen.

Nonbreaking hyphens prevent hyphenated words, numbers, or phrases from breaking if they fall at the end of a line of text. For example, you can prevent 555-0123 from breaking; instead, the entire item will move to the beginning of the next line. Click where you want to insert a nonbreaking hyphen.
Don't end a line on a hyphen in rag-right or centered text, unless the word that's breaking is a hyphenated compound that breaks at the grammatical hyphen. Don't let two lines in a row end in hyphens. Don't break words within a hyphenated compound.
To type a hard hyphen you will typically press the key to the right of the zero key (or if you want a non-breaking hyphen it's Opt/Alt + Cmd/Ctrl and do the same). To insert a soft hyphen, simply hold down Shift + Cmd/Ctrl and press the key to the right of the zero key.
Try using the non-breaking hyphen ‑
. I've replaced the dash with that character in your jsfiddle, shrunk the frame down as small as it can go, and the line doesn't split there any more.
