Culture Specific currency for a given culture

So I was working on a website and I used the following Javascript code

UsdAmount.toLocaleString(siteCulture,
      {style: 'currency', currency: 'USD'})
CadAmount.toLocaleString(siteCulture,
      {style: 'currency', currency: 'CAD'})

      

        
        
        
      

    

And it worked great with expected results

So,

Culture     Currency    Output
en-us       USD         $123.45
en-us       CAD         CA$123.45
en-ca       USD         US$123.45
en-ca       CAD         $123.45

      

        
        
        
      

    

But this feature doesn't work in Safari, so I can't use it.

So, I suppose I'll just do it server side in C # and pass the string

But this doesn't work for two reasons.

• I cannot go through two cultures, a systemic culture and a currency culture.

• Doesn't seem to work since

  4.ToString("C", new CultureInfo("en-us")) ==> "$4.00"
  4.ToString("C", new CultureInfo("en-ca")) ==> "$4.00"  // No CA$
  
        
  
          
          
          
        
  
      

So, any ideas for a currency formatting that works in all browsers?
