Russian symbols issue in R Learner Node

Hello,

R Learner, R Predictor, R Snippet, and R View nodes works incorrect with russian symbols. I connected Database Reader, which reads table with columns names in Russian, and R Learner. When you open R Learner node on the R Command tab all russian column names displayed incorrect. They displayed as dots. Other R nodes have the same issue.

Please advise.

Hi,
seems that you encountered a bug. This problem originates in the fact that we are trying to remove illegal characters from column names. As you might know R has some problems with special characters in syntactic names. While trying to keep only letters and numbers we were obviously a little bit too strict.

We will have a closer look into this problem and try to solve it as soon as possible. In the meantime the only workaround is to use latin characters - sorry. Thank you very much for this bug report!

Best regards,

Fabian
