Character limits, checked per platform
A styled letter is still one character, but it is a different character — and some platforms count differently once you paste. These are the caps the tool enforces when you pick a platform from the dropdown:
| Field | Limit | Notes |
|---|---|---|
| Instagram bio | 150 | The tightest place people use these styles. |
| Instagram name | 30 | Shown above the username — the field itself rejects most symbol styles. |
| Instagram caption | 2,200 | Feed cuts the caption at roughly 125 characters. |
| TikTok bio | 80 | Short — usually only one word plus a decoration fits. |
| TikTok caption | 2,200 | Same as Instagram. |
| X / Twitter post | 280 | Counted with X's own weights: most styled characters cost 2, links cost 23. |
| X / Twitter bio | 160 | Same weighted counting as a post. |
| Discord username | 32 | Most permissive platform for symbol styles. |
| Discord message | 2,000 | — |
| WhatsApp status | 700 | — |
| YouTube title | 100 | Truncates in search results around 60. |
| Facebook name | 50 | Facebook strips unusual characters from names. |
| LinkedIn headline | 220 | — |
Counting uses Unicode code points, not bytes and not UTF-16 units — that is what most platforms count. X is the exception: its own rules give most styled letters a weight of 2 and every link a weight of 23, so picking X applies those weights and the number can be higher than the raw character count. A style that adds a combining mark or a separator hits any cap sooner than the plain version of the same text.
