Chinese Martian Text Converter （火星文）

Decorate Chinese text as playful “Martian” writing (火星文) — homophone look-alikes such as 你 → 伱, traditional forms such as 门 → 門 and symbol-ish variants such as 的 → の. Three intensity levels mix those rule families; the Restore mode maps the variants back to an approximate original.
All processing happens locally in your browser — your data is never uploaded to any server.
Intensity:
Generate (to Martian): Each mapped character is swapped for its variant; characters outside the tables are kept unchanged.
Restore (approximate): Every variant in the output is mapped back to its most likely source character. The result is an approximation — some variant characters are also ordinary rare characters, so a few characters may be mapped too eagerly.

About the rule families:
Homophones (all levels) — near-sounding look-alikes: 我 → 莪, 好 → 恏, 是 → 昰.
Traditional forms (Medium +) — simplified characters are written in their traditional form: 门 → 門, 国 → 國, 爱 → 愛.
Symbol variants (Heavy) — kana-like and ornamented shapes: 的 → の, 了 → ㄋ, 我 → 硪.
Restore is approximate — this tool only maps the exact variants it produces, and a character such as 哋 could also appear as an ordinary rare character in your own text. Always proofread the restored text.
What is Martian text?

Martian text (火星文) is a youth writing style from the 2000s mainland-Chinese internet: ordinary characters are swapped for look-alikes — near-homophones (我 → 莪), traditional forms (门 → 門) or borrowed symbols (的 → の) — so the text stays readable at a glance but looks “alien” to standard readers.

Martian text is a substitution game on characters, not an encoding problem: the bytes are valid Chinese the whole time, which is why Restore can map every variant back — approximately, since some variants are also genuine rare characters.
