The problem is almost certainly caused by a difference in the default character encoind between your development system and the deployment server.
On our servers (and in most if not all Linux systems), the default character encoding is UTF-8.
The bast way around this issue is to use UTF-8 on both systems:
Read the file using as a binary file Read Resource, and translate it to a Text using Binary to Text. The latter plugin has an optional trigger <Enconding>. Use the encoding UTF-8.
You will need to convert your txt file to UTF-8. This is something most text editors can do. In the Studio (Eclipse) it is done by right clicking on the file in the Navigator view and choosing "Properties". The first screen has an option to select the encoding.
For best results, use the Firefox browser..
