UUEncode for ASS

This is a JavaScript implementation of the encoding algorithm for storing fonts or other binary data in Advanced SubStation Alpha (.ass) or SubStation Alpha (.ssa) files that are plain text.

Usage

``js
import { encode, decode } from "uuencode4ass";
import { readFile, writeFile } from "fs/promises";

const fontBuffer = await readFile("DejaVuSans.ttf");

const fontEncoded = encode(fontBuffer);
// !!%!!!!5!1!!"!"!2E:54;"0(C1!!!&-!!!!(%>%25;/\4$!!!";!!!!J(5%^46I$%.1!!!Q!!*[+
// 2V.61M(11&E!!++)!!!6XEV"6%CH-DB^!!#Y;!!!"DZ05S]S73VW,1!!PKA!!!"79WVB=0)*5SU!!,]!
// !!!#!!;2UZ!!$;E!!!!@ZG='>N=42W;A!!X*!!!!#L:W&T=!!(!!=!!.U]!!!!$'>M?79()#B!
// !!$>3!!)A=2I:7&E=4CD!!8QQ!!!!W;'BF91W@(]M!#6^%!!!!'BN>(AFINPH!!F@;!!!9::L:8O
// ...

const fontBufferDecoded = decode(fontEncoded);

await writeFile("DecodedFont.ttf", fontBufferDecoded);
```

Tests

This library is tested to produce the same result as the Aegisub's implementation of this encoding.
