Description

If you attatch an image with non-ascii name such as "café.jpg" to an issue and make an attempt to display as inline image, you will fail if text formatting is Markdown.

The cause of the defect is that Markdown formatter generates escaped file name. ApplicationController#parse_inline_attachments (source:trunk/app/helpers/application_helper.rb@14003#L637) expects a file name without escaping.

Textile:

!café.jpg!   =>   <img src="café.jpg" alt="" />

Markdown:

![](café.jpg)   =>   <img src="caf%C3%A9.jpg" alt="">

Quick workaround is the following:
