Why pasted text
arrives broken.
Plain explanations of the problems these tools solve — what actually causes them, and how to fix them properly.
Why text copied from a PDF has broken line breaks
Every visual line ending becomes a hard line break, words split across lines keep their hyphens, and justified text arrives full of double spaces. The cause is structural, not a bug in your PDF reader.
How to remove Markdown from ChatGPT, Claude, and Gemini output
Chat interfaces render Markdown, so what you see is formatted while what you copy is the raw syntax. Paste it somewhere that does not render Markdown and the asterisks show up.
What invisible Unicode characters are and why they break things
A form rejects an email address that looks perfect. Two identical strings compare as different. A search finds nothing. The usual cause is a character that occupies space in the data but paints nothing on screen.
Why PDF copy-paste splits words with hyphens
The hyphen was never part of the word. It was added by the typesetter to justify a line, and nothing in the PDF marks it as different from the real hyphen in "well-being".
How to paste without formatting in Word, Google Docs, Slack, and email
Copying puts several versions of your text on the clipboard at once. Most apps take the richest one, which is why pasted text arrives wearing the font, size, and colour of wherever it came from.
Fixing weird spacing after copy and paste
Pasted text with uneven gaps is usually four different problems wearing the same disguise. Telling them apart matters, because the fix for one makes another worse.
Em dashes, smart quotes, and the other tells of AI text
The em dash is the most discussed, but it is one of several typographic habits that make AI output look different from what a person types on a keyboard — and some of them break things.
What the tracking junk in a copied link actually does
A link you copy from an app is rarely just an address. The trail behind the question mark records which campaign reached you, which click was yours, and sometimes which account did the sharing.
Title case vs sentence case: which words get capitals
Every heading forces the choice, and the two conventions are not interchangeable: one follows grammar, the other follows a style sheet — and the style sheets disagree with each other.
