Using translations with Blockly

[lauracumming]

Describe the bug We have tried to implement other languages from Crowdin to Blockly, but it breaks Rapid Router when special characters are in a language.

This needs investigation so that we can use the translations.

Additional context We would like to test this with Catalan translation first.
