In trigger based action, while using custom script we may use:

script.sh "{HOST.HOST}" "{ITEM.KEY1}" "{ITEM.VALUE1}" "{TRIGGER.DESCRIPTION}"

Action will fail if:

1) Item 'key_' also contains double quotes like: input["input"]

2) Trigger title contains double quotes

3) A metric is some sort of XML/HTML text

A workaround sometimes is applicable - to use single quotes:

script.sh '{HOST.HOST}' '{ITEM.KEY1}' '{ITEM.VALUE1}' '{TRIGGER.DESCRIPTION}'

However, if '{ITEM.VALUE1}' will contains both single and double quotes, then the workaround will fail.

Please give a platform which allows to escape special characters while expanding trigger based macros.
