Resolving Encoding Issues with R's strsplit: A Step-by-Step Guide
The issue lies in the way you’re using strsplit and its interaction with the character encoding of your R console.
When running locally, it’s likely that your R console uses the system locale, which includes a specific character encoding (e.g., UTF-8). However, on an Ubuntu server, the default locale might be different, potentially affecting how characters are interpreted.
To resolve this issue:
Check Your Console Encoding: Before you start debugging, check what character encoding your R console uses by running getlocale() in your console or terminal.
