Example result

Encode UTF-8 characters without splitting a character across strings. Prefix each string with its byte count. RDATA cannot exceed 65,535 bytes.

Text abc with a 2-byte string limit becomes 02 61 62 01 63.

This exports RDATA, not a complete DNS record or zone-file quoting. Empty text becomes one zero-length string.
