Trilogy adapter incompatible with non-ascii column names about blazer HOT 4 CLOSED

Hi @D-system, thanks for reporting. It looks like it only causes an error when the query generates a chart:

SELECT 'a' AS "え", 1 AS "あ";   /* error */
SELECT 'a' AS "え", 'b' AS "あ"; /* no error */

but haven't identified the cause.

It looks like that's just the behavior of Action View, as this generates the same error:

<%= "え" %>
<%= "え".force_encoding(Encoding::US_ASCII) %>

Fixed in the commit above. Thanks again!

Another solution less dirty that can lives as a monkey patch for now and unblock the situation:

# config/initializers/blazer_utf8.rb
module Blazer
  class Result
    def columns
      @columns.map { _1.dup.force_encoding("utf-8") }
    end
  end
end

Thanks @ankane for the rapid fix 🙇‍♂️
