zabbix manual in several locations has plain doublequotes (") which get changed by dokuwiki to fancy ones (" and ")

this is (usually) not a problem in general text, but breaks copy-pasted strings like item keys, trigger expressions etc.

this conversion can be prevented by enclosing such strings in <nowiki> tags or %% tags - for example :

%%key["this is a parameter"]%%

whole manual should be reviewed for this and formatting should be changed in all places where strings would be expected to be copied and pasted in zabbix, commandline or other interpreted environments.
other doublequote conversions may stay as is.
