Forbidden Language Symbol Translator Online

Encode English text into the Forbidden Language symbol cipher, or decode symbols back into letters, using a fixed per-character table. Every mapped character is listed so you can verify the result, and unmapped characters are reported instead of silently dropped. Try it online.

What is the Forbidden Language Symbol Translator Online?

This is a text tool that converts ordinary English letters into a fixed set of symbols, and converts those symbols back into letters. It is a character cipher, not a translation between human languages: each letter is swapped for one symbol, one for one, and the period stays a period. The same table works in both directions, so you can encode a message and decode it again.

Key Features

Complete letter table. Every lowercase letter a–z has a symbol, and uppercase letters use the same symbols as their lowercase forms.
Two directions. Send English and get symbols, or send symbols and get letters back.
Visible mapping. The full table is shown so you can check any character yourself.
Preservation report. Spaces, digits, emoji and punctuation other than the period are kept as they are and listed, so nothing disappears without you knowing.
Round-trip check. Ask for a verification pass and the tool re-decodes its own output to confirm it matches your original text.

How to Use

Type or paste your English text and say you want it encoded, for example: encode: meet me at 8pm.
Read the symbol output in the code block, then copy it wherever you need it.
To go the other way, paste symbols and say decode, and the letters come back.

You can also ask for the mapping table, or ask what a single symbol stands for.

Example Use Cases

Novelty chat messages. Encode a short greeting for a Discord channel or group chat where a symbol cipher is a fun gimmick.
Decoding a received message. A friend sends you a line of symbols; paste it and ask for the forbidden language symbol translator to decode it back to English.
Checking a cipher table. Ask for the full letter-to-symbol list so you can compare it with a screenshot or an older message.

A quick before-and-after: hi. becomes °×. — h maps to °, i maps to ×, and the period stays a period.

Tips for Best Results

Say encode or decode explicitly when your text could be read either way; symbols like w and e are also ordinary letters.
Keep the original text if you plan to decode later, and use the round-trip check to confirm nothing changed.
Remember that digits, spaces and most punctuation are not part of the cipher and pass through unchanged.

FAQ

What input does it accept?
Plain text of any length in practical use. Letters and periods are converted; other characters are preserved and reported.

Is the output accurate?
The mapping is fixed and deterministic, so the same input always gives the same output. The tool shows the table and can verify a round trip, which is the strongest accuracy check available for a character cipher.

How is this different from some free text tools?
Many novelty cipher pages give you a box and an output with no explanation of the table and no report of what was left unconverted. This version publishes the mapping, states the direction it used, and tells you exactly which characters were not part of the cipher. It does not add features the original does not have, such as language translation or audio.

Does it translate other languages?
No. It substitutes characters. Text in another language will have its Latin letters substituted and its other characters left as they are.
