Velocity script adding a space before my URL

Question

Hi,

I don't fully understand the code below, but am hoping someone who does can tell me why there's a space being inserted before my URL when I apply this script token to an email.

Thanks!

#set($Calendly = $display.alt($OpportunityList.get(0).Calendly_OC_Checkin__c.trim(),""))

#if(   
  $Calendly.isEmpty() ||    
  $Calendly.indexOf(" ") == 1 
)
https://calendly.com/welcome-to-bench/account-check-in##  
#else
#set($Calendly = $Calendly.trim())
  $display.capitalize($Calendly.toLowerCase())## 
#end‍‍‍‍‍‍‍‍‍‍‍

You've got leading whitespace as well when you use the fallback value (check that indent on line 10). This code has no extraneous printable whitespace:

#set( $Calendly = $display.alt( $OpportunityList.get(0).Calendly_OC_Checkin__c.trim(),"" ) )
#if(   
  $Calendly.isEmpty() ||    
  $Calendly.indexOf(" ") == 1 
)
https://calendly.com/welcome-to-bench/account-check-in##
#else
#set( $Calendly = $Calendly.trim() )
$display.capitalize( $Calendly.toLowerCase() )##
#end‍‍‍‍‍‍‍‍‍‍

Note how there are spaces inside the parens. That's totally fine (and necessary to stay sane when coding) because it's not printable.

Line 2 is whitespace. Velocity doesn't insert whitespace, but it always *preserves* whitespace.
