Secret Message Invisible Ink Encoder

Description

Zero-width characters can carry an encoded text representation that may be unobtrusive in some renderers.

The representation is reversible and offers no encryption or confidentiality.

When to use Secret Message Invisible Ink Encoder

Use this tool to apply the stated secret message invisible ink encoder operation with an explicit input and unit basis.

How to use Secret Message Invisible Ink Encoder and how it works

Establish the text or game convention described above.
Enter actualText and run the tool.
Read result.convertedText using the output meanings below.
If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.

Input field	Meaning	Value type	Requirement
actualText	Text, on the basis specified in the algorithm.	string	required; further conditions in the algorithm

Convert each code point to a 21-bit binary string, concatenate, then replace zero with U+200B and one with U+200C. Output contains 21 encoding characters per input code point.

0 bit→U+200B; 1 bit→U+200C; 21 bits per code point

Apply the declared units, ordering and branch conditions.

Output field	Meaning	Value type
result	Object containing the declared output fields.	object
result.convertedText	Transformed text under the explicit rule above.	string

Limitations and assumptions

The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.

Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.

Alternative or Complementary methods

For a related operation, use Strikethrough Sarcasm Formatter. A combining stroke overlay can produce a visual strikethrough effect across text.

For a related operation, use Lipogram Letter Remover. A lipogram excludes chosen letters or characters from a text.
