Backslash are not exported correctly for .strings files

[nathanfallet]

Describe the issue

I have some strings in which I'm using LaTeX, so I have \. In Localizable.strings files, they need to be escaped as \\ (else they are treated as control chars).

My source strings is declared this way:

"example_card_1_content" = "The set of natural numbers is denoted as $\\mathbb{N}$:\n$$\\mathbb{N} = \\{0, 1, 2, 3, \\dots\\}$$";

After translations on weblate, it was exported like this:

"example_card_1_content" = "El conjunto de los números naturales se denota como $\mathbb{N}$:\n$$\mathbb{N} = \{0, 1, 2, 3, \dots\}$$";

So backslash are not escaped correctly!

Note that the same string is present in strings.xml files for Android, and it is exported correctly:

    <string name="example_card_1_content">El conjunto de los números naturales se denota como $\\mathbb{N}$:
 \n$$\\mathbb{N} = \\{0, 1, 2, 3, \\dots\\}$$</string>

I already tried

• I've read and searched the documentation.
• I've searched for similar issues in this repository.

Steps to reproduce the behavior

Import any Localizable.strings file with a string containing \\, translate to another language using weblate, and see the exported string with only \ instead of \\.

Expected behavior

I expected the exported string to contain \\, like in the source string, and also like the android xml generated file.

Additional context

After inspection, translate/translate#4618 should fix the problem.
