Cannot set working directory with special characters

[rachelwarnock]

Describe the bug
If a directory has a name with a special character, e.g. contains a letter with an umlaut, rb won't recognise it.

To Reproduce
setwd("/Users/warnock/Desktop/Project/Joël")

Expected behavior
R can handle the above directory name, would be cool if rb could do the same.

Computer info
Which OS are you using? Which version of RevBayes?
Same on Mac (11.7.2) and Windows.
RevBayes version (1.2.1)

Context
Discovered as I'm working with a student who has an "ë" in their name and hence their home directory name. They are not currently able to change this, so we're working around it.

Good to know! Hmm... I bet this relates to having UTF8-encoded strings for the filename.

So... I just tried this on Linux, and it worked fine. I tried "Joël" and also "的".

Does revbayes return a specific error message?
