Support line feeds in json JSON {}

Question

Could json JSON support linefeeds:

json JSON {
  "text": "Line 1\nLine 2\nLine 3"
}

(and probably other control symbols, like \t, etc.)?

Hi @boshka,

Json objects have an additional escape step (with same character \) therefore you have to escape \ with \\ itself.
This means you need e.g. \\n for a line break (details: see JSON two-character escape sequence​).

Yes, but that is a bug...
As mentioned on the end of:

It looks like that PlantUML "supports" (or is inconsistent) both version.
If it is defined via variables then you could use the version with one backslash, and in text you need 2 backslashes.



But if the grammar changes from "2 backslashes" to "one backslash" then a new notation would be required otherwise compatibility is lost.
