Frequently Asked Questions
Common questions about Unicode text decoration.
- Q1. Do font styles work for Hangul (Korean)?
- Hangul does not have alternate-font Unicode blocks, so styles like Bold or Script cannot apply to Korean characters. Instead, the tool offers decorative frames (stars, hearts, brackets, sparkles) and Wide spacing for Hangul. All 30+ styles apply to Latin letters and digits.
- Q2. I pasted into KakaoTalk and see boxes instead of styled text.
- Kakao renders text using the system font (Samsung on Android, Apple SD Gothic on iOS). Fraktur and some Script variants lack glyphs in those fonts, showing as boxes. Switch to Bold, Sans Bold, Circled or Fullwidth — those render correctly on virtually all devices.
- Q3. Do Unicode characters count toward the Instagram bio 150-character limit?
- Yes — the output is plain text, so it counts toward the 150-character limit. Mathematical alphabet blocks like Bold and Script use surrogate pairs (2 UTF-16 code units per character), so the effective character cost is higher than the visible letter count.
- Q4. Can I use these styles in a Discord nickname?
- Mostly yes. Discord bans @, #, :, backtick and a few other characters, and combining marks (zalgo-style) may be filtered by server moderators. Fraktur, Monospace and Bubble work reliably.
- Q5. Does using styled text on Twitter/X hurt SEO?
- Search engines treat "Hello" and "𝐇𝐞𝐥𝐥𝐨" as different strings. If discoverability matters, keep keywords in plain text and apply styles only to decorative parts of the post.
- Q6. What is the difference between Bold and Sans Bold?
- Bold is the mathematical bold serif block (letters have serifs). Sans Bold is the mathematical bold sans-serif block (no serifs). Sans Bold generally looks cleaner on mobile system fonts.
- Q7. How does the Share URL work?
- The input text is base64-encoded into a
?t=…URL parameter. Nothing is stored on the server — the recipient's browser decodes it locally and pre-fills the same input. Be careful not to share sensitive text this way. - Q8. The Strikethrough / Underline style covers the whole character on some devices.
- U+0336 (combining long stroke overlay) draws a horizontal line over each glyph. Some mobile fonts misalign the stroke above or below the character center. If this happens, use Underline (U+0332) instead, or avoid combining styles for that platform.
- Q9. Does text with emoji get converted correctly?
- Emoji are not in the mapping tables and pass through unchanged. For example "Hello 🎉 2026" becomes "𝐇𝐞𝐥𝐥𝐨 🎉 𝟐𝟎𝟐𝟔". Decorative frames wrap the entire string, including emoji.
- Q10. Does this site collect personal data?
- Input text is stored only in browser local storage. It is never sent to a server unless you click Share URL. Visit statistics use anonymous Google Analytics only.
