Translation problem

[kelvin_han]

Recently I want to translation dotproject into chinese simplified. While I take steps as what have said in this forum. Finally I find that the tranlated dotproject is unrecognized , in some places it is translated into chinese, but most of it is unknow font? Using the "view the sources.." It shows "
href="?m=companies">&sup1;&laquo;&Euml;&frac34; | href="?m=projects">&Iuml;&icirc;&Auml;&iquest; | href="?m=tasks">&Egrave;&Icirc;&Icirc;&ntilde; | href="?m=calendar">&Egrave;&Otilde;&Agrave;&uacute; | <a href="?m=files">&Icirc;&Auml;&frac14;&thorn; "
How can I solve this problem? Thank for your help
