Impossible to generate well formated POT files when a String with \" is used

Godot version

System information

Godot v4.1.stable - Windows 10.0.22621 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1050 (NVIDIA; 31.0.15.3667) - Intel(R) Core(TM) i5-8300H CPU @ 2.30GHz (8 Threads)

Issue description

When generating a POT file using Godot Editor, if the String contains double quotes, its entry in the POT file will be wrong (see below).

Steps to reproduce

Create this script:

extends Control


func _ready():
	
	var a: String = tr("\"Problematic\" string")
	print(a)

And then generate a POT file from it. You will get something like:

# LANGUAGE translation for Bugs for the following files:
# res://main.gd
#
# FIRST AUTHOR < EMAIL @ADDRESS>, YEAR.
#
#, fuzzy
msgid ""
msgstr ""
"Project-Id-Version: Bugs\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8-bit\n"

#: main.gd
msgid ""Problematic" string"
msgstr ""

The problem cames from the extra double quotes inside the string, they will raise an error when generating a PO file.

A possible solution would be to make:

extends Control


func _ready():
	
	TranslationServer.set_locale("fr")
	var a: String = tr("\\\"Problematic\\\" string")
	print(a)

Therefore, the POT file:

# LANGUAGE translation for Bugs for the following files:
# res://main.gd
#
# FIRST AUTHOR < EMAIL @ADDRESS>, YEAR.
#
#, fuzzy
msgid ""
msgstr ""
"Project-Id-Version: Bugs\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8-bit\n"

#: main.gd
msgid "\"Problematic\" string"
msgstr ""

But then, the string is not recognized. This is the PO file with an extra entry added manually:

# LANGUAGE translation for Bugs for the following files:
# res://main.gd
#
# FIRST AUTHOR < EMAIL @ADDRESS>, 2023.
#
msgid ""
msgstr ""
"Project-Id-Version: Bugs\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"Last-Translator: Automatically generated\n"
"Language-Team: none\n"
"Language: fr\n"
"Plural-Forms: nplurals=2; plural=(n > 1);\n"

#: main.gd
msgid "\"Problematic\" string"
msgstr "TEST0"

msgid "\\\"Problematic\\\" string"
msgstr "TEST1"

Then print(a) prints TEST1 instead of TEST0.
