## Text Encoder
### What it is
Encodes a string by converting special characters into escape sequences
### How it works
<!-- MANUAL: how_it_works -->
The Text Encoder takes the input string and applies Python's `unicode_escape` encoding (equivalent to `codecs.encode(text, "unicode_escape").decode("utf-8")`) to transform special characters like newlines, tabs, and backslashes into their escaped forms.
The block relies on the input schema to ensure the value is a string; non-string inputs are rejected by validation, and any encoding failures surface as block errors. Non-ASCII characters are emitted as `\uXXXX` sequences, which is useful for ASCII-only payloads.
<!-- END MANUAL -->
### Inputs
| Input | Description | Type | Required |
|-------|-------------|------|----------|
| text | A string containing special characters to be encoded | str | Yes |
### Outputs
| Output | Description | Type |
|--------|-------------|------|
| error | Error message if encoding fails | str |
| encoded_text | The encoded text with special characters converted to escape sequences | str |
### Possible use case
<!-- MANUAL: use_case -->
**JSON Payload Preparation**: Encode multiline or quoted text before embedding it in JSON string fields to ensure proper escaping.
**Config/ENV Generation**: Convert template text into escaped strings for `.env` or YAML values that require special character handling.
**Snapshot Fixtures**: Produce stable escaped strings for golden files or API tests where consistent text representation is needed.
