Bun transforms hexadecimal escape sequences representing Unicode characters into their actual character equivalents

[lleqsnoom]

What version of Bun is running?

1.1.42+50eec0025

What platform is your computer?

Linux 6.10.14-linuxkit aarch64 unknown

What steps can reproduce the bug?

When bundling CSS files, Bun transforms hexadecimal escape sequences representing Unicode characters into their actual character equivalents, followed by an extraneous backslash (). This alteration can cause icons and special symbols to render incorrectly.

.fa-shop-slash {
  --fa: "\e070";
  --fa--fa: "\e070\e070";
}

.fa-store-alt-slash {
  --fa: "\e070";
  --fa--fa: "\e070\e070";
}

What is the expected behavior?

.fa-shop-slash, .fa-store-alt-slash {
  --fa: "\e070";
  --fa--fa: "\e070\e070";
}

What do you see instead?

.fa-shop-slash, .fa-store-alt-slash {
  --fa: "\\";
  --fa--fa: "\\\\";
}

this is a very odd change

edit: my bad, i was specifically looking at \n, but the post concerns other characters.
this change occurred in Bun v.1.1.35
Bun v1.1.34 does not convert \n

honestly, i'd prefer that no escape characters get converted. i assume this is a space saving technique, but i can't imagine it's saving all that much space
