Iso8859 europe check

iso8859-europe-check · version 1.0.0 · Numbers & math · free, no key needed

Check ISO-8859-2, -3, -4, -10, -13, or -16 using pinned published character tables.

Use when you need to: check ISO 8859 European text · ISO 8859 part 2 check · Latin 3 character set check.

Decide before calling

Read the versioned contract and the supported scope below. Reuse iso8859-europe-check@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-europe-check@1.0.0 for check ISO 8859 European text. 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

• check ISO 8859 European text
• ISO 8859 part 2 check
• Latin 3 character set check
• Latin 4 bytes check
• Latin 6 data check
• Latin 7 text check
• Latin 10 check conversion

Not supported

• automatic encoding detection
• multibyte or stateful character encodings
• Unicode normalization

Behavior

• The encoding field explicitly selects one pinned ISO/IEC 8859 edition; no heuristic detection occurs.
• Undefined bytes are diagnosed by zero-based byte offset; unrepresentable text is diagnosed by Unicode scalar offset.
• max_output_bytes measures UTF-8 bytes in the compact JSON serialization of the returned object; oversized results fail with limit_exceeded.
• Disclaimer: format transform only; provides no confidentiality, integrity, or authenticity.

Input

• encoding (one of "iso-8859-2", "iso-8859-3", "iso-8859-4", "iso-8859-10", "iso-8859-13", "iso-8859-16", required)
• bytes_base64 (string, required): max length 5464

Output

• valid (boolean, required)
• undefined_offsets (array of integer, required): max items 4096; each min 0
• undefined_bytes_hex (array of string, required): max items 4096; each pattern ^[0-9a-f]{2}$
• standard_version (string, required)
• data_version (string, required)
• edition (string, required)

Limits

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

    "undefined_offsets": [],
    "undefined_bytes_hex": [],
    "standard_version": "ISO/IEC 8859 parts 2:1999, 3:1999, 4:1998, 10:1998, 13:1998, 16:2001",
    "data_version": "iso-8859-europe-2026-10-24",
    "edition": "ISO/IEC 8859-2:1999"
