Thanks Mitko,
The charset_recode suggestion does work.
http("v1_lab") does not:
HT008: http requires string, blob or string session as argument 1
Is there a more convenient way to output UTF8 values without the explicit
charset_recode as all VSP text output from my sparql queries will be
UTF-8.
It is also clear I do not grasp the types of strings expected and returned
at various places.(wide vss narrow). A pointer to documentation would be
welcome.
(I know sprintf('%s', "v1_lab") works, I could write a procedure I
suppose)
Thanks,
Lourens
