I am using MetaFun (Lua code) to create METAPOST commands from an XML file. One of the issues I am running into that in METAPOST I have to handle strings with " characters in them and METAPOST doesn’t like those. The argument using the string Foo "Bar” Foo

Use correct left quotation marks or \quotation{…}.

I’m not hard coding the string, I’m reading it from an XML. So, whatever I do, I need to do it by manipulating the string. E.g. if the string I read contains Foo "Bar” Foo your suggestion means I have to programmatically change that to Foo \quotation{Bar} Foo which is too complicated, given that I don’t have regular expression replace at my disposal. I might be able to change al “ instances into something else by walking through the string and building a new one. G
