Error including hyphen in graph legend text

[Mark Finnis]

This seems to be a bug, but I am unable to include a hyphen (to indicate a numerical range) in a legend label, e.g.

stcurve , cif at1(cfs14=1) at2(cfs14=2) at3(cfs14=3) at4(cfs14=4) ///
tit("") name("crr_cfs14", replace) ///
xtit("ICU Hours") xlab(0(72)288) ///
ytit("Cumulative Discharge from ICU") ///
lp(solid solid solid solid) ///
lc(purple green orange red) ///
leg(order(1 "CFS:1-2" 2 "CFS:3-4" 3 "CFS:5-6" 4 "CFS:7-8") ///
col(2) size(small) ring(0) pos(4) symx(*.5))

Returns:

2" 2 "CFS:3 invalid name
r(198);

If I remove, or replace the hyphen with any other alpha-numeric char, there is no issue.

Any advice would be appreciated!

Seems like stcurve *! version 6.7.7 12nov2020 need to be fixed. Report this issue to [email protected]

(you might have an older version of stcurve to use, or someone reading the statalist might propose fixes)

I just updated my Stata installation and I can replicate this. Prior to updating, the issue did not occur. As a workaround, you can replace "-" in the code with

`=ustrunescape("\u2010")'

Also, as suggested by Bjarte, report the issue to Tech Support.
