Should I use special Unicode characters for punctuation marks such as ellipsis in programs?

Question

Unicode has a set of characters for punctuation such as ellipsis (…), En-Dash (–) and others. It's believed that using these characters improves typography and therefore visual appearance of the texts.

Many development tools, Visual Studio included, support Unicode and so I could easily make use of these characters in programs resources - dialogs, etc.

Are there any reasons for not doing so?

Answer 1

If you're absolutely certain that the users' machines will have the fonts needed to display those characters properly (and e.g. for dialogs on Windows you should definitely be able to rely on that), then, go right ahead!
