[Q&A]: How can we learn the locale used in webr?

[homerhanumat]

What's your question?

As best I can tell from online documentation, when R is installed via WASM the default locale is a C-type, and it is unclear to me that a user can change this. But render this document and run the code-fields:

---
title: "Test"
format: html
filters:
  - webr
---


```{r}
# On my machine, the locale is en_US.UTF-8:
Sys.getlocale("LC_COLLATE")
```

```{webr-r}
# webr-r will also report en_US.UTF-8
Sys.getlocale("LC_COLLATE")
```



```{r}
## in en_US.UTF-8 the following evaluates to TRUE
"a" < "B"
```

```{webr-r}
# but the WASM installation appears to use a C-type locale:
"a" < "B"
```

How can one get webr to report the locale that is actually being used?

The behavior is the same on several browsers.
