Why does SAS/Studio "eat" some of my output?

[Tom]

I was trying to see how UNICODEC() converted some UTF-8 characters into strings that I could transmit with 7-bit ASCII.

When I looked at my PROC FREQ output in SAS Studio the version generated with the 'PAREN' style was gone or invisible.

But when I sent the same text to RTF, PDF, LISTING or LOG it is is visible.

 The FREQ Procedure
                                                                        Cumulative    Cumulative
 __hex__    __paren__    __esc__    __ncr__    Frequency     Percent     Frequency      Percent
 -----------------------------------------------------------------------------------------------
 E28099     <u2019>      \u2019     &#8217;           4       50.00             4        50.00  
 E289A4     <u2264>      \u2264     &#8804;           1       12.50             5        62.50  
 E289A5     <u2265>      \u2265     &#8805;           3       37.50             8       100.00  

So why is the output window not showing the <u2019> strings?

Is it because it thinks they are some type of HTML tag?  If so why?

Does this mean that any character string I try to print might be missing some characters if they just happen to have a < and > in that order?

Perhaps it is just the PROC FREQ output?
This code does not have the issue with the HTML output window that SAS/Studio uses.

data test5;
  file print;
  length char paren $10 ;
  do char='E28099'x,'E289A4'x,'E289A5'x ;
     paren=unicodec(char,'paren');
     put char= paren= ;
  end;
run;

HTML tags are enclosed in angular brackets. Browsers treat strings like yours as "a tag I do not understand" and discard them. This is a safety measure so that older browsers don't stumble over later tags.

HTML compatible output should use &lt; and &gt; instead of the brackets.

Yes. They are HTML tag . If you want display them , you need a special STYLE .

data have;
input (__hex__    __paren__    __esc__    __ncr__ ) (: $80.);
cards4;
 E28099     <u2019>      \u2019     &#8217;   
 E289A4     <u2264>      \u2264     &#8804;    
 E289A5     <u2265>      \u2265     &#8805; 
;;;;


proc report data=have nowd style(column)={protectspecialchars=yes} ;
run;
