Getting a list of translated strings

Godot Version

Question

I am using a CSV file for storing all of the strings for my game in different locales. What I want to make is a function that takes a RegEx string and returns all the strings (in the current locale), whose keys match the given RegEx. It goes like this:

static func get_all_strings(key_regex: String):
	var found_strings: Array[String]
	var cur_locale = TranslationServer.get_locale()
	var translation = TranslationServer.find_translations(cur_locale, true)[0]
	var regex = RegEx.create_from_string(key_regex)
	for key in translation.get_message_list():
		if regex.search(key):
			var translated_key = TranslationServer.translate(key)
			if !translated_key.is_empty():
				found_strings.append(translated_key)
	return found_strings

The problem is: translation that I get from find_translations is OptimizedTranslation. Therefore get_message_list() is always empty. I tried to search a way to get it unoptimized and failed. Is there any workaround?

Re-import your csv files with Compress disabled.
