Somtimes you'll find some errors trying to merge Prototype and jQuery librarires. If the problem isn't into your code you can try creating groups.

For example:

Into your layout definition, change the addItem action and add the instruction.

<action method="addItem"><type>skin_js</type><name>js/jquery.js</name><group>jquery</group></action>

All the files with the same group will be merged into a separated file. Some times solve this kind of problems.

Magento 1.8 CSS File Merge – Fix Data URIs Problem

In iphone.css magento also uses data URI but without quotes, try to do the same

background: #fafafa url(data:image/svg+xml;base64, PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHZlcnNpb249IjEuMSIgeD0iMHB4IiB5PSIwcHgiIHdpZHRoPSI2cHgiIGhlaWdodD0iM3B4IiB2aWV3Qm94PSIwIDAgNiAzIiBlbmFibGUtYmFja2dyb3VuZD0ibmV3IDAgMCA2IDMiIHhtbDpzcGFjZT0icHJlc2VydmUiPjxwb2x5Z29uIHBvaW50cz0iNS45OTIsMCAyLjk5MiwzIC0wLjAwOCwwICIvPjwvc3ZnPg==) no-repeat;

In your case instead of

/url\\(\\s*(?!data:)([^\\)\\s]+)\\s*\\)?/

you should use

/url\\(\\s*(?![\"\']?data:)([^)]+)\\)/

Magento 1.9 Disable Calendar CSS or Merge with All CSS Files

In order to properly erase calendar.css, you need to create a module. Inside your layout update xml file, you need to add this:

File : app/design/{frontend|adminhtml}/base/default/layout/{layout_update_xml_file}.xml

<layout>
    <default>
        <reference name="head">
            <action method="removeItem"><type>js_css</type><name>calendar/calendar-win2k-1.css</name></action>
            <action method="removeItem"><type>js</type><name>calendar/calendar.js</name></action>
        </reference>
    </default>
</layout>

Here I am not sure from which area you want to erase those calendar related js/css files. So use either frontend or adminhtml according to your need.
