What is Markdown and how do I convert it?

Markdown is a lightweight plain-text format with symbols like # for headings and ** for bold. PromptSpace has a Markdown Preview tool, a Markdown-to-HTML converter, an HTML-to-Markdown converter, and a Strip Markdown tool — pick the one that matches your direction of conversion.

How does Line Sorter Online handle Unicode and emoji?

Line Sorter Online operates on UTF-8 text with full Unicode support. Emoji, accented characters, RTL scripts (Arabic, Hebrew), CJK (Chinese/Japanese/Korean), and combining marks are counted and transformed correctly — no data loss on non-ASCII input.

How do I sort lines alphabetically or remove duplicates?

Use the Line Sorter tool: paste your text, pick ascending or descending, and optionally toggle "remove duplicates" and "case-insensitive". Trailing whitespace and empty lines are handled predictably.
