what does an em dash symbol look like?
triple
the en dash – always with spaces in running text when, as discussed in this section, indicating a parenthesis or pause – and the spaced em dash both have a certain technical advantage over the unspaced em dash. most typesetting and word processing expects word spacing to vary to support full justification. alone among punctuation that marks pauses or logical relations in text, the unspaced em dash disables this for the words it falls between. this can cause uneven spacing in the text, but can be mitigated by the use of thin spaces, hair spaces, or even zero-width spaces on the sides of the em dash. this provides the appearance of an unspaced em dash, but allows the words and dashes to break between lines. the spaced em dash risks introducing excessive separation of words. in full justification, the adjacent spaces may be stretched, and the separation of words further exaggerated. en dashes may also be preferred to em dashes when text is set in narrow columns, such as in newspapers and similar publications, since the en dash is smaller. in such cases, its use is based purely on space considerations and is not necessarily related to other typographical concerns.
