TM ART's Chart server might show the error "Message = No response" in the System Health screen if unsupported characters are used in Project names. The Chart server logs will also show an entry such as: java.lang.Exception: ChartEngine: 2 - Too few values entered Problematic characters can include but are not limited to unicode characters such as Umlauts, long dashes, etc. This limitation is within a 3rd party component which has not published a list of problematic characters. Take for example the 2 characters below, although they appear similar they are treated differently by the 3rd party engine in the Chart server. The longer hyphen will cause the error "Message = No response" if used in a project name, the shorter minus sign will work normally. To resolve an issue if a hyphen is used for instance, all that is needed is to change any project name to use a shorter minus sign and reload the System Health page.
