Unicode Text Styler

Most styles use the Mathematical Alphanumeric Symbols block (U+1D400–U+1D7FF), which contains full bold, italic, script, fraktur, double-struck, sans-serif and monospace alphabets meant for mathematics; a few letters were encoded earlier in Letterlike Symbols (ℋ ℎ ℂ ℕ ℝ …) and the page uses those code points instead. Small capitals come from the IPA and phonetic extensions, fullwidth from the CJK compatibility forms, circled and squared letters from Enclosed Alphanumerics, and upside-down and mirrored text from look-alike letters across the Latin, IPA, Greek, Cyrillic and Hangul blocks, reversed.

These are different characters that happen to look styled. A screen reader may read 𝐇 as "mathematical bold capital H", read nothing, or read the whole word letter by letter; search does not match them; some fonts lack them and show boxes. The styles marked accessible — fullwidth, strikethrough, underline and spaced — keep the original letters (with combining marks or spaces), so they stay readable. Use the others for display only.

Zalgo stacks combining marks above, below and through each letter. The level sets how many marks per letter; the seed feeds a small pseudo-random generator so the same text, level and seed give exactly the same marks. Accented and non-Latin letters have no counterpart in the tables and pass through unchanged. Nothing leaves the browser; the same four anonymous usage counts as the rest of the site apply.
