terminate called after throwing an instance of 'char const*'

after calling `languages()` i get this:
```
terminate called after throwing an instance of 'char const*'
```
My platform is very specific and old ( https://github.com/Kobo-InkBox/inkbox ) so this can be an issue
I will simply use the rust library for now, reporting this to let others know they are not alone

Start with the languages() call and try to reproduce the reported uncaught `char const*` termination on the InkBox platform linked in the issue. The report names no source file or test; identify where that call fails, determine whether the behavior is specific to the old platform, and document a confirmed diagnosis or reproducible fix.
