All content converted to WideString or what? Yes, the string starts as a plain ByteString and once you add the € it gets automagically converted to a WideString, but you pay a huge price in performance: it involves the usage of global #become: each time, which is dead slow (Spur will help IIUC). A possible solution is to somehow start with a WideString from the beginning (or force it before doing all elements one by one). > But I really want to rendery euro symbol > > Thanks > > Hilaire > > > Le 31/12/2015 14:32, Hilaire a écrit : >> Hello, >> >> I am experiencing a slow down rendering a large table report: >> >> The table report is more than 240 lines.
