How do I check for quotation marks in liquid?

I am working with an input string like 'James "Jim" Smith' with a person's nickname being double quoted within a string. I have been trying to find if a person has a nickname by using the contains operator, but it never finds entries with double quotes. As an example:

<-- Name - James "Jim" Smith -->
{% if Name contains '\"' %}
   Do Something
{% else %}
   Always gets here
{% endif %}

How can I search for the literal double quote in a string using contains (or split)?

Did some testing and it can be done, although it's not pleasant.

{% if stringVarWithQuote contains '"' %}
  <p>Never true</p>
{% endif %}

{% if stringVarWithQuote contains '\"' %}
  <p>Never true</p>
{% endif %}

{% if stringVarWithQuote contains """ %}
  <p>Always true (even without a quote character in the string)</p>
{% endif %}

{% if stringVarWithQuote contains """" %}
  <p>Always true (even without a quote character in the string)</p>
{% endif %}

{% if stringVarWithQuote | url_escape contains '%20' %}
  <p>Always true (even without a quote character in the string)</p>
{% endif %}

{% assign stringVarWithQuoteCompare = stringVarWithQuote | remove: '&quot;' %} 
{% if stringVarWithQuote != stringVarWithQuoteCompare  %}
      <p>This works!</p>
    {% endif %}

From my testing no comparison to a string literal will work. Often the comparison will always be true, which is easy to overlook in testing. The only way I could get this to work was to create a second variable using the 'remove' filter to strip out quote characters, then compare the two variables. I am unimpressed with this language.

My approach to solve the problem:

{{ post.title | remove: '&quot;'}}

Remove: '"' seems working to me

If none of the above works for you, try this. It did it for me when removing double quotes:

| remove '"'

With Liquid map I have observed \\\" translates into \"

I have read about escaping both single and double quotes by doubling them and had some success myself doing this...

In my own example I was trying to remove quotes from a string And the following did NOT work:

{{ post.title | remove: """ }}

However this DID work:

{{ post.title | remove: """" }}

I think that would work in your if statement:

{% if name contains '""' %}

But am not sure how that would work where you are assigning the string or if you need to escape it in your "assign"

You don't need to escape it. The following will return true:

{% assign name = 'James "Jim" Smith' %}
{% if name contains '"' %}
  true
{% else %}
  false
{% endif %}
