Hi,
My JSON is like this
posts": [{ "id": 1, "type": "post", "slug": "post\_slug", "title": "Hello ” world “", }]
When I try to display the title using newText api. The text output the ” and “ which should be converted to quotes symbols " "
How can I output the string converting both ” and “ with proper character?
Well, I just did a quick & lazy solution
local title = posts[i].title title = title:gsub("%”", "\"") title = title:gsub("%“", "\"")Hey Alyosef,
I suppose you are using json.decode() to retrieve the strings from the json file?
If yes, I think the problem is the escape sequence you are using.
As you can read in the JSON specs ( http://json.org/ ) special characters are used as the following:
\b Backspace (ascii code 08) \f Form feed (ascii code 0C) \n New line \r Carriage return \t Tab \" Double quote \\ Backslash caracter
Hope that helps 
Thank you for your answer. Yes, I am using json.decode() to retrieve the strings from the json file. You are right if I have control over what I am getting in the JSON file, then I can easily escape the special characters.
Ah ok, so you got a JSON file that was meant for and uses escape sequences from another language (like HTML for example)?
Yes, you are correct.
Well, I would try the following.
Use string.gsub (as you already did) but not again and again for every sequence you want to check for, instead use a table.
Additionally you use a pattern, to find the sequences you need.
This is explained in the docs ( https://docs.coronalabs.com/api/library/string/gsub.html ) but I will give it a short try:
local replacements = { ['”'] = '\"', ['“'] = '\"', } local pattern = "((%&#)%d+;)" function sanitizeString(text) return text:gsub(pattern, replacements) end
Hope that helps
Thank you, it definitely helps.
