Old issue has come back

[OlegNadymov]

After updating from 1.3.8 to 1.6.0.2 the issue has come back:
#195

Again I can't use inner double quoutes in my expression. But I have a condiserable number of similar expressions.
Can you fix it again?

@OlegNadymov
Can you please provide a full code example?

For instance this expression gives me "Syntax error":

var innerFilter = System.Linq.Dynamic.Core.DynamicExpressionParser.ParseLambda<System.Linq.Dynamic.Core.Tests.Helpers.Models.User, bool>(null, true, "UserName = \"\"test\"\"");

More exception info:

@OlegNadymov
In your case, You need to set StringLiteralParsingType to StringLiteralParsingType.EscapeDoubleQuoteByTwoDoubleQuotes

See
https://dynamic-linq.net/advanced-configuration#stringliteralparsingtype-since-v1.4.3

This is exactly what I needed. Thank you!
