How to use it
- Type or paste the text in Text.
- Set Marks per letter if you want a stronger effect in the glitch style.
- Press Copy under the style you want and paste it where you need it.
How the lines are made
A combining mark is drawn over, under or through the character before it, instead of standing on its own. The page writes one mark after each letter, digit and punctuation mark: U+0336 COMBINING LONG STROKE OVERLAY for the strikethrough, U+0338 COMBINING LONG SOLIDUS OVERLAY for the slashed style, U+0332 COMBINING LOW LINE for the underline, U+0333 COMBINING DOUBLE LOW LINE for the double underline and U+0305 COMBINING OVERLINE for the overline. The names are those in the Unicode code chart Combining Diacritical Marks.
strikethrough = each letter, digit or mark + U+0336
underline = each letter, digit or mark + U+0332The glitch style
The glitch style adds the number of marks you choose after each letter, digit and punctuation mark. The marks come from the same block, U+0300 to U+036F, in a fixed order, so the same text and the same number always give the same result. The page allows up to 12 marks; more would hide the letters.
What does not change
- Spaces, tabs and line breaks get no mark. A combining mark placed on a space would draw a line between two words.
- A combining mark that is already in the text is kept as it is.
- Some apps do not draw combining marks: they show boxes, or the marks sit beside the letter. Screen readers may read the marks by their names or skip them, so do not use these styles for text that must be read aloud.
Worked example: Sale 50
With the strikethrough and the underline, the words Sale 50 come out as the table shows. Each letter and digit has its own mark, and the space between the two words has none, so each word is struck or underlined on its own.
| Style | Result |
|---|---|
| Strikethrough | S̶a̶l̶e̶ 5̶0̶ |
| Underline | S̲a̲l̲e̲ 5̲0̲ |
Frequently asked questions
Is this real bold or strikethrough formatting?
No. The line is a separate Unicode mark that follows each character, so the text carries no formatting. A place that cannot draw combining marks shows the letters with the marks misplaced, or as boxes.
Why is there no line over the spaces?
A mark on a space would draw a long line between two words, so the page leaves spaces without a mark. The line stops at each space, which keeps the words apart.
Can I paste these styles into any app?
Often yes, because the characters are ordinary text. Some sites remove or move combining marks, so check the result on the site where you will post it.
What does the glitch style do?
It adds the number of marks you choose after each letter, and the marks stack above, below and across the letter. For the same text and the same number the result is always the same, so you can copy it and keep it.
Is my text sent to a server?
No. The styles are computed in your browser. Nothing you type is stored or sent anywhere.
Why not use the formatting of the app instead?
Many places, such as a bio box or a comment field, accept only plain text. Combining marks are then the only way to get a line through or under the letters.
