Closes gh-3 This is a complicated issue, but I'll do my best to explain it here. By default, Haml encodes its templates as Encoding.default_internal, which is usually UTF-8. This means that strings printed to the template should be either UTF-8 or UTF-8-compatible ASCII. So far, all well and good. Now, it's possible to have strings that are marked as ASCII-8bit, but which aren't UTF-8 compatible. This includes valid UTF-8 strings that are forced into an ASCII-8bit encoding. If one of these strings is concatenated to a UTF-8 string, Ruby says "I don't know what to do with these non-ASCII characters!" and throws an encoding error. I call this sort of string "fake ASCII." This is what was happening in the referenced GitHub issue (or at least in the sample app Adam Salter created at http://github.com/adamsalter/test-project/tree/haml_utf8). The template was UTF-8 encoded, and it was being passed a fake ASCII string, marked as ASCII-8bit but with UTF-8 byte sequences in it, and it was choking. The issue now becomes: where is this fake ASCII string coming from? From the database. The database drivers used by Rails aren't Ruby 1.9 compatible. Despite storing UTF-8 strings in the database, the drivers return fake ASCII strings. The best solution to this is clearly to fix the database drivers, but that will probably take some time. One stop-gap would be to call `force_encoding("utf-8")` on all the database values somewhere, which is still a little annoying. Finally, the solution provided in this commit is to set `:encoding => "ascii-8bit"` for Haml. This makes the Haml template itself fake ASCII, which is wrong but will help prevent encoding errors.
