Adding this for completeness:
If you don't want to use CSS, you can use <nobr>text with space</nobr> - reference here
For pure text blocks, I believe that html formatting tags that are no longer tags, such as <i> , <b> , <nobr> and the like, are valid for use. For content related to site structure , use <em> , <strong> and <span class=""> .
