This tool decorates plain text by randomly attaching combining accent marks to its letters, producing a stylised metal-umlaut or light glitch effect. The intensity is adjustable, and the effect is fully reversible because the underlying letters never change.
How it works
Combining diacritics in the Unicode range U+0300 to U+036F render on top of the character before them. The tool walks the text and, for each letter, decides whether to decorate it:
for each letter:
if random() < density:
append 1 to N random marks from U+0300 … U+036FHigher density and more marks per letter create heavier stacking. Spaces and punctuation are skipped so word boundaries stay legible.
Example and tips
A light setting turns GERA TOOLS into something like GĖRA TÔŌLS, while a heavy setting stacks several marks per letter. Keep density low for readable headings and high for a chaotic effect. To recover the original, paste the result into a diacritic stripper — it will normalise and strip the marks back to clean text.
What combining diacritics actually are
Most people encounter diacritics as fixed accented letters: é in French, ü in German, ñ in Spanish. These are precomposed characters — a single Unicode code point that includes the base letter and the mark together. Combining diacritics are different: they are separate code points that attach visually to whatever precedes them. Unicode defines over 100 combining marks in the U+0300–U+036F range, covering the accents used in dozens of scripts and phonetic notation systems.
Because they are separate characters, they can stack arbitrarily — you can place two, three, or more on a single base letter. Heavy Zalgo-style text works exactly this way: it stacks so many marks that the text overflows its line-height and appears to “bleed” into surrounding lines. This tool keeps the count much more controlled.
Use cases — when decorative diacritics work well
Band and artist names. The “metal umlaut” (putting an umlaut on letters that would not normally have one — Mötley Crüe, Queensrÿche) has been a visual signifier of metal and hard rock since the 1980s. This tool makes it trivial to try the look on any name.
Game usernames and display names. Many games and social platforms allow Unicode in display names, letting players distinguish their handle from others who have taken the plain-ASCII version. A light diacritic on one letter can make a username both unique and still pronounceable.
Design mockups and placeholder text. Designers sometimes need text that “looks like a language” without being actual readable content — decorative diacritics produce exactly that effect quickly, without resorting to Lorem Ipsum that might mislead stakeholders reading the mockup.
Social media bios and headings. On platforms that support Unicode (most do), a stylised word in a profile bio or a post heading stands out in a feed of plain text.
Reversibility — how to get the original text back
Because combining marks are appended after the base letters without changing them, the original text is embedded in the output. Any tool that strips Unicode combining marks — including the companion diacritic stripper on this site — will recover it exactly. The process is: decompose to NFD normalization, then remove any character in the Unicode “Mark, Nonspacing” (Mn) category. The base letters remain intact.
This distinguishes combining-diacritic decoration from tools that substitute entirely different lookalike characters (homoglyphs), which cannot be cleanly reversed.
