Checkmark emoji on different platforms

Hi duddys 

Is  your  checkmark using UNICHAR to render it?  These characters are rendered differently by different  browsers. You can use SVG in icon conditional formatting for a greater control on colors.

SVG Checkmark = 
VAR _value =
    CALCULATE ( SUM ( 'Table'[Value] ) )
VAR _threshold = 1500
VAR _test = _value > _threshold
VAR width =
    IF ( _test, 80, 0 )
VAR height =
    IF ( _test, 80, 0 )
VAR stroke1 =
    IF ( _test, 5, 0 ) --increase to make the border thicker
VAR stroke2 =
    IF ( _test, 10, 0 ) -- increase to make the checkmark thicker
VAR __Prefix = "data:image/svg+xml;utf8," --note: after hitting reply this line will  probably return a different value so refer to the screenshot
VAR SVG = "<svg width='100' height='100' xmlns='http://www.w3.org/2000/svg'>
  <!-- Background square -->
  <rect x='10' y='10' width='" & width & "' height='" & height & "' 
        fill='limegreen' stroke='darkgreen' stroke-width='" & stroke1 & "' />
  <!-- Checkmark -->
  <path d='M30 50 L45 65 L70 35' 
        fill='none' stroke='white' stroke-width='" & stroke2 & "' stroke-linecap='round' stroke-linejoin='round' />
</svg>"
RETURN
    __Prefix & SVG

Please note that based on testing, SVG as icons will not be rendered if hexadecimal values are used thus the limegreeen and darkgreen colors. Also you need to change the dimension of the SVG elements to 0 if you don't want to show them as, if for example, if i simply use IF(_test, _Prefix & SVG), those do not meet the _test condition will still return in Firefox a missing image icon instead of nothing.

Please see sample pbix.
