A special (or unprintable) character is a stylized character that falls outside the standard ASCII set and commonly occurs when copying/pasting from Microsoft products such as Word or Excel.
Examples of special/unprintable characters include:
- Smart Quotes (“…”)
- en dash (–)
- em dash (—)
- Smart Ellipsis
- Smart Commas
- zero width spaces
When adding TCPA language to your website, ensure that you are not using any characters outside the standard ASCII set (32-126). For your convenience, here is a link to determine which characters fall within the standard set and what others are considered special/unprintable characters and can therefore result in mismatches.
