I've resumed trying to get the callback to plslabelfunc working in Ada (example 19). I'm returning a pointer to an array of chars that is "length" (which seems to be hardwired to 40) long, including the null character terminator. The significant characters are right-justified within the array (except for the null). I've tried to emulate the behavior of snprintf. However, every time the callback happens, I get
UTF-8 string is malformed: UTF-, aborting operation I haven't fully dug into the logic leading up to this output line but it seems to be a series of tests for font or character handling. The above results happen when postscript or svg is selected--the output files are created but without labels. FWIW, if I select the null or fig output device, these error messages do not appear. If X- Window is the output (and I run from xterm in OS X), there are no error messages and the plots are created but without labels. Any ideas?
