```ruby
# coding: utf-8

require 'sketchup'
require 'set'

Encoding.default_external='utf-8'

```

when i install sketchup into the directory with chinese character, the sketchup plugin loads with errors when i require set. I guess the set library is in the installation’s directory. but the path has other characters not ascill. so is it a bug for sketchup?

When i replace the “Set” with “Sketchup::Set”, i don’t require set in standard library. but when i require ‘logger’, it also has the same problem. what can i do?

Before any requires, try adding

```ruby
$LOAD_PATH.map! { |d| d.dup.force_encoding('UTF-8') }

```

You may have to repeat it if the $LOAD\_PATH array changes. I believe it’s a Ruby issue. SU 2017 also seems to have the same issue, the above fix works for it. Don’t have SU 2015 installed…
