Why limit file contents to just strings?

[danielo515]

Hello.
I have a situation where I want to zip a buffer that contains binary data.
I tested the file with the underlying library (zip-stream) and it works correctly without problem. However, you only accept strings as input, and your library deletes any content that is not a string:

express-easy-zip/index.js

Lines 82 to 83 in a2bed82

	return new Promise(function(resolve, reject) {
	data = clean.cleanOnlyString(data);

Why this limitation when the zip-stream library is capable of handling Buffer | Stream | String?
