Good to know

Frequently asked questions
Are the line numbers saved into the file?
No. Line numbers are a visual aid in the editor only and are never written into the downloaded .txt file.
Why is the text shown in a monospaced font?
A monospaced view keeps characters and columns aligned, which suits logs, code-like text and README files.
What encoding does the .txt use?
The file is handled as UTF-8 plain text, which preserves accented and non-Latin characters correctly.
