Hi list, I'm running SBCL 0.9.13.52 (same error with 0.9.13 release) and TBNL 0.9.10. I've got a simple page set up that I need to simply print the return value of an external function. That function returns a list containing UTF-8 characters. I've set *show-lisp-errors-p* to T, here is the error: encoding error on stream #<SB-SYS:FD-STREAM for "standard output" {A6877B9}> (:EXTERNAL-FORMAT :ASCII): the character with code 20170 cannot be encoded. I had done some digging on google and found someone in a similar situation with TBNL, and he tried changing his locale LC_ALL to a utf-8 one. The above (:EXTERNAL-FORMAT :ASCII part was :ASCII only after I set my locale to UTF-8, beforehand it was :LATIN-1, which I do not understand. Here is the code, if it helps: (in-package :tbnl-foo) (setq *dispatch-table* (list (create-prefix-dispatcher "/tbnl/foo" 'foo) 'default-dispatcher)) (defun foo () (let ((foo (jalat::search-hash "hello"))) (with-html-output (*standard-output*) (:h2 (str foo))))) (setq *dispatch-table* (nconc (mapcar (lambda (args) (apply #'create-prefix-dispatcher args)) '(("/tbnl/test/" foo))) (list #'default-dispatcher))) The external function simply returns a list of plists containing UTF-8 characters. I also tried setting *tbnl-default-external-format* to no avail. Thanks guys, -- Dan Beauchesne dbeauchesne -at- gmail -dot- com
