Greetings,
I have recently been having a particular issue dealing with how IDL
encodes its international characters and how they are displayed. My
goal is to be able to have a widget_text() box which can display
international characters.
I have encountered the following issue on a Mac running IDL 7.0 and a
Linux box running IDL 8.1
I can create a string as follows using the compose key on my keyboard:
IDL> s='ñ'
And I can get my IDL command line to properly output the value of the
string
IDL> print, s
ñ
Now I notice that this character is stored as a 2 character string and
my encoding is properly transforming it to my screen when I print it
out
IDL> print,strlen(s)
2
IDL> print, strmid(s, 0, 1)
?
IDL> print, strmid(s, 1, 1)
?
IDL> print, strmid(s, 0, 2)
ñ
Now the problem arises when I want to use this character in a widget
or a plot as such
IDL> plot, [0], /nodata, title=s
The title of the plot gets set as a capital A with a tilde followed by
a plus-minus sign.
Is there any way in which I can change the encoding with which plots
and widgets interpret symbols?
I also note that textoidl() does not appear to be working within the
context of widgets. Is this a common occurrence or am I just doing
something incorrectly?
Thanks!
