Use checks, bullets, arrows, currency signs, units and legal marks accurately in business and technical documents.
The short version
Start here if you only have one minute. The full guide below explains each point.
Follow the field's rules
Use the mark your workplace, style guide, or subject expects.
Pair status marks with words
A check or warning is clearer when a short label explains the result.
Treat rights marks with care
Copyright and trademark signs do not create rights by themselves. Check the real rules.
01
Prefer established conventions
Use a currency sign with a clear amount. Add the currency code when readers span more than one country. Keep units with their numbers, and use the standard unit character rather than a lookalike.
The degree sign closes up against the number. It stays separate from the unit letter. These are small rules, but specialist readers notice them straight away.
02
Checks and status marks
A check can mean done, approved, or applies here. A cross can mean wrong, missing, or closed. None of that is obvious on its own.
Define what each mark means the first time you use it. Then keep to that meaning for the whole document.
- Pair glyph and status word
- Keep column alignment consistent
- Provide a legend for unfamiliar marks
- Check monochrome printing
03
Copyright and trademark notation
© marks a copyright notice. ® is for registered marks in places that recognise registration. ™ is used for unregistered claims.
Place them as the law of your country expects. Do not scatter them for decoration. In legal text, the position carries weight.
✦Symbols can summarize established information; they cannot create a legal status that does not exist.
04
Make exported documents resilient
Check that fonts are embedded when you export a PDF. Open slides on the machine that will present them.
Font substitution can turn a symbol into a blank box in the final file. The editor will not warn you. Only the export shows it.
05
Consistency matters more than the individual choice
In a long document, which characters you choose matters less than using the same ones throughout. Mixing hyphens and en dashes in number ranges reads as careless. So does using three different bullets across your lists.
Write the decisions down. Which dash for ranges. Which bullet at which level. One short style note settles the argument once.
- Ranges take an en dash, not a hyphen
- Choose one bullet character per list level and keep to it
- Decide between the multiplication sign and the letter x, and apply it consistently
06
Documents that outlive their software
Business documents get converted, archived, printed and reopened in software that did not exist when they were written. Every conversion can drop an unusual character.
Favour the conventional character where one exists. Keep decorative marks out of headings, defined terms and anything a reader might search for.
07
Where symbols earn their place in a document
Symbols earn their place when they replace a repeated phrase, not a word. Units, currency signs and maths relations all do that.
They stop earning it the moment they become decoration. An ornament in a heading costs you search, translation and accessibility for no gain.
Professional notation by decision risk
A symbol is useful when the audience shares its convention. As the consequence of misunderstanding rises, pair the mark with more explicit language.
| Context | Acceptable shorthand | Required safeguard |
|---|---|---|
| Internal checklist | ✓ Done / ⚠ Review | Define the status labels once and do not rely on color. |
| Measurement | 20 °C or 5 kg | Use the field's spacing and unit standard; retain the numeric value. |
| Legal or rights notice | ©, ™ or ® | Confirm the jurisdiction and actual registration status. |
| Medical or safety instruction | A familiar supporting pictogram | Write the hazard, consequence and action in plain language. |
A Unicode name verifies character identity, not authority to make a legal, medical or certification claim.

Questions, answered
Should a currency sign come before the number?+
Placement varies by currency and locale; follow the audience's convention or use an ISO code.
Can I use ® for any brand?+
No. It generally signals a registered mark and should not be used without the relevant status.
Are emoji professional?+
Tone and audience decide; text symbols are often easier to align in formal documents.
