Thanks ;-) Unrelated, but pdf/A-4 will require that there is no /Info dictionary. In pdftex Thanh implemented \pdfomitinfodict to suppress it. Could luatex please follow? Ulrike

(^^^^fffd works) In luatex we have this in the string converter

if (val == 0xFFFD) utf_error(); because 0xFFFD is the intial value. In luametatex I just return 0xFFFD on an invalid utf but if we want to be compatible in luatex we need to issue that message on an invalid characters so we can start out with initial -1 and change it to if (val < 0) utf_error(); that way FFFD will fall through Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
