The Science of "Fake" Fonts (Unicode)
When you see a profile on Twitter or TikTok using a font like 𝐇𝐞𝐥𝐥𝐨 or 𝐻𝑒𝑙𝑙𝑜, they aren't actually changing the "font-family" of the website. They are using Mathematical Alphanumeric Symbols from the Unicode standard.
Computers see the letter "A" (U+0041) and the bold letter "𝐀" (U+1D400) as completely different characters.
⚠️ Accessibility Warning
Screen readers (used by visually impaired people) often struggle to read these "fancy" styles. They might read "𝐇𝐞𝐥𝐥𝐨" as "Mathematical Bold Capital H, Mathematical Bold Small E...". Therefore, avoid using these styles for important information like dates, addresses, or critical announcements. Use them sparingly for usernames or aesthetic bio taglines only.
Why do captions break on Instagram?
Instagram's algorithm aggressively trims "whitespace" to save database space and keep UI clean. If you hit "Enter" twice to create a gap, Instagram often collapses it back to a single line.
Our tool solves this by inserting a specific invisible character known as the Braille Pattern Blank (U+2800). Since this character is not technically a "space" (it's a symbol), Instagram treats it as content and preserves the line break.
