Cyberchef: Bug report: 0D (binary) is silently replaced with 0A (binary)

[nmantani]

Hello,

0D (binary) in the input box is silently replaced with 0A (binary) in the output box.
And 0D 0A (binary) sequence is also replaced with 0A (binary).
These replacements break data integrity.
If input data is a dragged and dropped file, the replacements does not occur.

How to reproduce

1. Input "0D 0D 41 0D 0A" (text, without quotes) in the input box.
2. Use "From Hex" recipe. Data in the output box is "0D 0D 41 0D 0A" (binary). This output is correct.
3. Press "Move output to input" button.
4. Change the recipe to "To Hex". Data in the output box should be "0d 0d 41 0d 0a" (text),
   but it is actually "0a 0a 41 0a" (text). This output is corrupted.

This is a "feature" of HTML textarea elements and there is nothing we can do about it without writing a custom DOM element.

This is one of the reasons why files are loaded in the way that they are - to preserve carriage return bytes.

If someone has a solution, I'd be glad to hear it.

Oh, it is because of a feature of HTML textarea elements. I understand that it is very hard to resolve.
Thank you very much for your explanation.
