Lists and bullets
Read this before you use it on a whole post
These characters are Unicode maths symbols, not real bold text. Screen readers often read them letter by letter or skip them, and LinkedIn search will not match them. Use them for a single word or a short header, never a whole post.
How LinkedIn bold actually works
LinkedIn gives posts no rich-text editor, so there is no real bold to apply. What every LinkedIn formatter does instead is substitute Mathematical Alphanumeric Symbols, a Unicode block that contains bold, italic, script and monospace versions of the Latin alphabet. The glyphs look like formatted text and paste anywhere, because they are just characters.
Where you can paste it
- Posts and comments. Works everywhere, and a single bold phrase genuinely helps a long post scan.
- Headline and About. Works, but this is where the search cost bites: a bolded keyword in your headline is invisible to LinkedIn search.
- Company pages and newsletters. Works the same way, since the styling travels in the characters.
The honest trade-off
These characters are not text as far as assistive technology is concerned. A screen reader may announce “mathematical bold capital H, mathematical bold small o…” one glyph at a time, or say nothing. LinkedIn search will not match them either, so a bolded keyword stops being a keyword. Both costs are acceptable for one emphasised phrase in a post. Neither is acceptable for a whole post, and any tool that does not tell you this is doing you a disservice.
Frequently asked questions
How do you bold text in a LinkedIn post?
LinkedIn has no formatting toolbar for posts, so bold is done by swapping normal letters for Unicode mathematical characters that look bold. Type your text here, select the words you want, click Bold, then copy the result and paste it into LinkedIn.
Does bold text hurt accessibility or reach?
It can do both. Screen readers often read these characters one letter at a time or skip them entirely, and LinkedIn search will not match them. Use them for a single word or a short header, never for a whole post.
Will the formatting survive copy and paste?
Yes. The styling is part of the characters themselves rather than markup, so it pastes intact into LinkedIn posts, comments, headlines and the About section.
Can I get my plain text back?
Yes. Paste styled text into the box and click "Plain text" to convert every styled character back to normal letters.
Where this stops working, which no formatter tells you
Accented letters do not convert. The Unicode block these styles come from covers unaccented A to Z and 0 to 9 and nothing else, so José bolds to 𝐉𝐨𝐬é with the accent left plain. Anyone whose name, company or language carries a diacritic gets a broken word and no warning. 4 of the 9 styles also have no numerals (italic, bold italic, sans italic, script), so a year or a figure stays upright mid-line.
| Style | Letters | Digits | Accents |
|---|---|---|---|
| Bold | Converted | Converted | Left as typed |
| Italic | Converted | Left as typed | Left as typed |
| Bold italic | Converted | Left as typed | Left as typed |
| Sans bold | Converted | Converted | Left as typed |
| Sans italic | Converted | Left as typed | Left as typed |
| Script | Converted | Left as typed | Left as typed |
| Monospace | Converted | Converted | Left as typed |
| Underline | Mark added | Mark added | Mark added |
| Strikethrough | Mark added | Mark added | Mark added |
We measure this rather than describe it: every cell above is produced by running the real formatter over a probe string as this page renders, so the table describes the tool you are about to use. Underline and strikethrough work differently: they leave every character exactly as typed and add a combining mark after it. That is why they handle accents and numerals when the others cannot, and also why they double the character count of everything they touch.
Formatting is the easy part
Unicode bold makes a post look considered. Content Drifter makes it BE considered: written in your voice from your own past posts, timed to when your audience actually reads LinkedIn, and published without you opening the app.
