Excel Custom Ribbon Group - Special Characters in the label

Question

I have a custom Ribbon with buttons in Excel. I use XML below... Is there a way to use special characters: an ampersand or quotation marks in the description (label)?

<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui"> 
  <ribbon startFromScratch="false"> 
    <tabs> 
      <tab id="CustomTab" label="Custom"> 
        <group id="TransactionFilter" label="Transaction Sort and Filter"> -- I would like "Transaction Sort & Filter"
          <button id="bSetFilter" imageMso="Filter" size="large" 
                  label="Filter" 
                  onAction="SetFilterFromRibbon"/> 
          <button id="bClearFilter" imageMso="FilterClearAllFilters" size="large" 
                  label="Clear Filter" 
                  onAction="ClearFilterFromRibbon"/> 
        </group> 
      </tab> 
    </tabs> 
  </ribbon> 
</customUI> 

I have tried repeating the character twice, putting a star in front of it. Nothing worked so far
