Iso8859 semantic encode

iso8859-semantic-encode · version 1.0.0 · Encoding & checksums · free, no key needed

Encode logical Unicode text as ISO-8859-6 Arabic, ISO-8859-8 Hebrew, or ISO-8859-11 Thai bytes.

Use when you need to: encode Arabic text to ISO bytes · encode Hebrew text to ISO bytes · encode Thai text to ISO bytes.

Decide before calling

Read the versioned contract and the supported scope below. Reuse iso8859-semantic-encode@1.0.0 when your input, required output and limits match it. Choose another approach for an unsupported operation.

Explain the choice

"I can use iso8859-semantic-encode@1.0.0 for encode Arabic text to ISO bytes. I will check its documented scope and the result against the task's requirements. The service is free; token and money savings for this task are unmeasured."

Supported

• encode Arabic text to ISO bytes
• encode Hebrew text to ISO bytes
• encode Thai text to ISO bytes
• logical Unicode to legacy byte stream
• replace unencodable Unicode scalars
• write ISO part 6 byte data

Not supported

• Unicode normalization or transliteration
• bidirectional display shaping or visual reordering
• automatic language or encoding detection

Behavior

• Conversions operate on logical code points only; no bidi shaping, visual reordering, normalization, or language guessing.
• Strict mode rejects the first undefined byte or unrepresentable character; replacement mode uses U+FFFD when decoding and byte 3f when encoding.
• Omitted mode means strict. Check reports every undefined byte offset.
• Base64 must be canonical and bytes are reported in lowercase hexadecimal diagnostics.
• The max_input_bytes limit is the UTF-8 byte length of text; max_items is its Unicode scalar count.
• Disclaimer: format transform only; provides no confidentiality, integrity, or authenticity.

Input

• encoding (one of "iso-8859-6", "iso-8859-8", "iso-8859-11", required)
• text (string, required): max length 4096
• mode (one of "strict", "replacement", optional)

Output

• bytes_base64 (string, required): max length 5464
• replacements (integer, required): min 0; max 4096
• standard_version (constant "ISO/IEC 8859-6:1999; ISO/IEC 8859-8:1999; ISO/IEC 8859-11:2001", required)

Limits

• max input bytes: 4096
• max output bytes: 16384
• max items: 4096

Example

Request input:

{
  "encoding": "iso-8859-11",
  "text": "ไทย"
}

Response:

{
  "result": {
    "bytes_base64": "5LfC",
    "replacements": 0,
    "standard_version": "ISO/IEC 8859-6:1999; ISO/IEC 8859-8:1999; ISO/IEC 8859-11:2001"
  }
}
