Computers can display a wide variety of characters. Sometimes it can be confusing to identify exactly which character is being shown, as many look very similar.
I recently encountered this very issue. It involved a simple dash connecting two numbers, for example “1-4.” At least, I assumed it was a simple dash. In reality, there are many different types of dashes, and this can become a problem when converting a document to PDF.
Below is a brief overview, just so you can see the differences:
- en-dash: –
- em-dash: —
- hyphen: ‐
- hyphen-minus:﹣
- minus-sign: −
