Unicode character will not display in sgplot output

fastb — Wed, 27 Sep 2023 19:16:05 GMT

Hi,

I need to have unicode character 3251 (circled number 21) appear as a symbol on a graph in sgplot.

However, an open square appears on the graph instead of the circled 21 when I create the graph.

It appears that this is happening because the font I am using does not support that unicode character.

I tried sevral different fonts and nothing worked.

Is there a specific font that I need to use for this, or are ther any other solutions?

Thanks!

Where is it supposed to appear? Title text, axis label, axis tickmark label, data label in the body of the graph?

Show the actual code and/or value of the variable that you are using.

Depending on your current SAS session settings and where you want to use the value you may have to have a value like

(*ESC*){unicode <codevalue>}

which sometimes means creating a new variable that is longer to hold all those characters and may require the value to be in hex notation such as {unicode '03B2'x} which is the greek letter beta

Hi ballardw,

The characters need to appear as marker symbols in the body of the graph.

Below is the code where I used symbolchar to create the each symbol with the unicode character.

This works fine for the symbols with numbers 1 through 20.

However, starting with 21 it is a different charcater code set and everything 21 and above does not work.

Thanks!

I think you are running into this from the Symbolchar statement online help:

Tip This statement attempts to access the specified Unicode value in the current font. Some fonts do not support accessing characters by using their Unicode value. Other fonts support only a limited set of Unicode values. If the Unicode value is not accessible, then this statement might be ignored or a nonprintable character might be substituted.

I had the same result you do with all of the fonts I tried so it may be that many font "designers" don't see a need for the circle numbers past 20.

If you find something where it resolves properly try using that Font in a TEXTATTRS with the Family option. Since fonts aren't the same across installations I am not sure which to suggest.

/*Here is a workaround way.*/
data have;
 set sashelp.class;
if age<14 then char='21';
 else if age<15 then char='22';
  else char='23';
run;

proc sgplot data=have nocycleattrs noautolegend;
