I don't think there is, but it can be done.

Looking at the source file of the sm plugin, it just detects when someone typed a RTL character (via UTF-8, which is really small list of languages (about 10) and just flips the relevent part of the string.

Since goldsrc supports UTF-8 text starting from steampipe update back in Aug 2013, it shouldn't be a problem.
