Stand Out with Unicode Styles
Stop blending in with plain text. Our bold text generator uses Unicode mathematical alphanumerics to create eye-catching styles that work on Instagram, Twitter, LinkedIn, TikTok, Facebook, and Threads - no special apps required.
Whether you need professional serif styles for LinkedIn thought leadership or playful bubble text for TikTok comments, our real-time social preview shows exactly how your styled text will appear before you post, including platform-specific character limits and truncation points.

Pro Tips:
- Bold Sans or Italic Sans styles work on nearly every platform and are screenreader-friendly
- Some styles like Script or Fraktur may not display correctly on older devices
- Check the "Live Social Preview" to see exactly how your text will appear before posting
- Platforms like Twitter have strict character limits (280) - decorated text may count as more characters
- Use "See More" platforms (Instagram, LinkedIn, Facebook) strategically by front-loading key info
- Bubble and Flip styles are playful but may reduce accessibility - use sparingly for emphasis
Common Use Cases

Frequently Asked Questions
๐งTechnical Details & Unicode Characters
Unicode Mathematical Alphanumerics
Bold and italic text on social media isn't achieved through traditional HTML formatting (like <b> or <i> tags). Instead, it uses Unicode Mathematical Alphanumeric Symbols - a special range of characters (U+1D400 to U+1D7FF) originally designed for mathematical notation.
Example Character Transformation:
| Original | Unicode | Bold Sans | Unicode | Script | Unicode |
|---|---|---|---|---|---|
| A | U+0041 | ๐ | U+1D5D4 | ๐ | U+1D49C |
| a | U+0061 | ๐ฎ | U+1D5EE | ๐ถ | U+1D4B6 |
| 5 | U+0035 | ๐ฑ | U+1D7F1 | 5 | U+0035 |
Note: Script style doesn't have dedicated number glyphs, so digits remain unchanged.

Character Coverage & Unicode Gaps
Not all Unicode styles have complete character sets. Some alphabets have gaps where certain letters use special slots or don't exist at all:
Script & Fraktur Gaps:
The Script and Fraktur styles have historical gaps due to conflicts with pre-existing Unicode symbols:
Our tool automatically handles these gaps by using the correct Unicode slots.
Double Struck Inconsistencies:
Double Struck (blackboard bold) uses special slots for common mathematical symbols:
This can cause slight visual inconsistencies in stroke weight. For uniform "outlined" text, use Bubble instead.
Number & Digit Coverage:
Most mathematical styles include digits 0-9, but decorative styles don't. Our tool handles this automatically:
Platform Character Limits & Truncation
Instagram Reel/Post
Truncates at 125 chars ("...more"), max 2,200 total
X (Twitter) Post
Hard limit, no truncation - visible character counter
LinkedIn Post
Truncates at 140 chars ("...see more"), max 3,000 total
TikTok Video Caption
Hard limit, no truncation or expansion
Threads Post
No truncation, visible character counter
Facebook Post
Truncates at 400 chars ("See More"), max 63,206 total
Pro Tip: Our Live Social Preview highlights truncation points and shows real-time character counts. For platforms with "See More" (Instagram, LinkedIn, Facebook), front-load your most important message, emoji, or CTA within the visible portion to maximize engagement.
Accessibility & Screenreader Behavior
Unicode mathematical alphanumerics have varying levels of screenreader support. Our tool categorizes each style as "Safe" or "Unsafe" based on accessibility:
Safe Styles (Screenreader-Friendly):
These styles are announced correctly by most screenreaders (JAWS, NVDA, VoiceOver):
Unsafe Styles (Accessibility Issues):
These styles may be announced character-by-character, incorrectly, or not at all:
Recommendation: For important content (announcements, legal text, accessibility-required posts), use platform-native formatting instead of Unicode styles.
Best Practices for Accessibility:
- โ Use "Safe" styles for main content, "Unsafe" styles only for decorative emphasis
- โ Avoid using Unicode styles in alt text or image descriptions
- โ For critical CTAs (links, buttons), use plain text with platform-native bold/italic
- โ Test your content with a screenreader before posting (VoiceOver on iOS, TalkBack on Android)
- โ Consider adding plain text equivalents in replies or comments for accessibility
Combining Diacritics & Text Decoration
Underline and Strikethrough styles use Unicode Combining Diacritical Marks - special zero-width characters that modify the preceding character:
How Combining Marks Work:
A (U+0041) + โฬฒ (U+0332) = Aฬฒ
A (U+0041) + โฬถ (U+0336) = Aฬถ
Note: Each combining mark adds +1 to the character count. "Hello" (5 chars) becomes "Hฬฒeฬฒlฬฒlฬฒoฬฒ" (10 chars with underlines).
Platform Rendering Differences:
- โข Instagram: Renders combining marks correctly on iOS, may have alignment issues on Android
- โข Twitter/X: Excellent support, renders consistently across devices
- โข LinkedIn: Good support, but may show extra spacing on desktop
- โข TikTok: Limited support - combining marks may appear as separate characters
- โข Facebook: Inconsistent - works well on web, variable on mobile apps
Character Count Impact:
Because combining marks are separate characters, decorated text uses roughly 2x the character count of plain text. This is especially critical on platforms with strict limits:
Our Live Social Preview accounts for this automatically - watch the character counter when using these styles!
