Salesforce import handling of names with bad characters

[chrisinf]

What type of report is this:

Q	A
Bug report?	Yes
Feature request?	No
Enhancement?	No

Description:

Salesforce data might contain characters such as a backslash. While this data imports to mautic successfully, it does not seem to be escaped or encoded correctly when passed back into the salesforce API (during the "Mautic to Salesforce" phase).

I believe the following error comes from the Salesforce call itself, i.e. this is not a PHP/code-related error:

Updating/creating companies from Mautic to Salesforce
About 0 to update and about 15654 to create/update
     3/15654 [>---------------------------]   0%

  [Mautic\PluginBundle\Exception\ApiErrorException]
  Solutions','Mxxxxxxxxxxxy Solutions','md\PAxxxxxxxxxxx Services','Mxxx'
                                      ^
  ERROR at Row:1:Column:710
  Invalid string literal 'md\PAxxxxxxxxxxx Services'. Illegal character sequence '\P' in string literal.

If a bug:

Q	A
Mautic version	2.11.0
PHP version	7.0.24

Steps to reproduce:

1. Save a record in salesforce with a company name or contact position/title containing characters which will not pass SOSL/SOQL query validation (i.e. use restricted characters). In the problematic case it was a string containing \P (md\PBB Zxxxhxhx for example).

2. Run the mautic:integration:fetchleads command and pull the record from step 1

Log errors:

1. This log is specific to this request (its the same one referenced above)

2. This log was found prior to the previous log. Looks like the same issue with a different piece of (similarly unescaped) data.
