Tried to Download worksheet files from my sage notebook in my Ubuntu 14.04 and got the following error messages. Any idea how to fix the problem?

Found the reason to the problem: it's an UniCodeError as follows.

This could be a problem in your path, conceivably - see this answer.

Otherwise it's likely that there are some unusual characters elsewhere (in your title?) causing the problem... the last command there both reads and writes a file. Giving us more information about the exact setup, path, titles etc. would help diagnose this.

Worksheets are opened in the browser normally without any problems.

My worksheet are done/saved in sage-format. They don't contain any special characters (language US-en). They contain plots. The worksheet names are for example "Impulses", "Astrea Polars", "Production node equations" etc.
