Avoid Two Spaces
The older of us, who started exercising their ten (or two) fingers on a typewriter as opposed to a computer keyboard, may have developed the habit of putting ‘two spaces’ between sentences. At the time, ‘two spaces’ were fine as it helped the visual impression of the document. Now, in times of computers and electronic typesetting, the concept of ‘two spaces’ has become obsolete: Depending on the position of the space character, the surrounding characters, and other factors, the spacing is adjusted automatically by the text layout software to produce the finest visual results.
When converting Word documents to HTML, Help Producer intentionally preserves a sequence of spaces by converting them into non‑breaking spaces. However, non‑breaking spaces may negatively impact text wrapping when used improperly; therefore, you should consider placing a single space between sentences.
