Text Processing
Encode and decode with less-common text codecs: Base65536 (binary → dense Unicode) and netstring (self-delimiting framing). Base85 is intentionally not rebuilt (already covered).
Details
Two text codecs that the existing base32/base45/base58 tools do not cover. Base65536 (by qntm) packs every two bytes into one of 65,536 Unicode code points — denser than Base64, useful when you want binary-as-text over a Unicode-friendly channel and don't mind exotic-looking output. netstring (D. J. Bernstein's self-delimiting format) frames data as

Tool usage guide
Encode or decode text with Base65536 or netstring. Base65536 converts UTF-8 text into dense Unicode characters, while netstring frames text as a byte length, colon, data, and trailing comma.
Background
A developer needs to represent the text hello using the Base65536 codec.
Problem
Create a compact Unicode string that can be decoded back to the original text.
How to use
Enter hello in Text, select Base65536 as Codec, and select Encode as Direction.
Text: hello; Codec: Base65536; Direction: EncodeOutcome
The tool returns a dense Unicode representation of the five UTF-8 input bytes.
Background
A backend developer needs a self-delimiting representation of a short text value.
Problem
Add the UTF-8 byte length and framing markers around hello.
How to use
Enter hello in Text, select netstring as Codec, and select Encode as Direction.
Text: hello; Codec: netstring; Direction: EncodeBase65536 encodes UTF-8 bytes into dense Unicode characters and can decode them back losslessly.
A netstring uses the format <byte-length>:<data>, such as 5:hello,.
The length counts UTF-8 bytes, not characters.
The decoder validates lengths and trailing commas and reports malformed segments.
Choose Encode to create Base65536 or netstring text, and Decode to recover the original text.
Outcome
The result is 5:hello, with the byte length, colon, data, and trailing comma.
