Decimal numbers will become truncated on json parsing when OS system locale is not US-English

[milosh-dev]

I have Ubuntu 20.04 OS and my system locale is set to et_EE.UTF-8 (which means that in my system thousands are separated by space and decimals by ",").

When I use jsonlite::fromJSON(text) in R for parsing json, all numbers with decimals (77.87, 23.45, etc.) will become integers (77, 23, etc.). The problem is probably trackable down to R_parse function.

When I set my system locale to US-English the jsonlite::fromJSON parses json fine. The problem exists with my particular locale (Estonian).

For all the remaining programs, and my other R code I have had no problems with my system locale. Also, parsing my json with alternative R packages (like jsonify::from_json) works fine, so the issue exists only with jsonlite.

Unfortunately, I depend on jsonlite functionality, so substituting with jsonify library is not not an option. Any help is needed.
