Hi,

I'm hoping to include an arrow symbol in a character string.  Something 
like:

"Regular ->  Banked / OT"

But I would like a "nicer" arrow.  I was looking at unicode options and 
there is a ➔ unicode U+2794.  I was thinking that I might be able to 
accomplish this with UNICODE2STR() with the correct however I'm not sure 
how to format the unicode string.  So far I getting some really nice ?? 
or ???.

Any guidance would be appreciated.

Thanks... Jonathan

If for pushbutton - render text as graphic and display graphic on top of push
button;


xBase is still not Unicode compilant so the ?? are probably resoult of that.
Which is shame, as many problems are starting to emerge out of lack of support
for that. (mind not on western alphabets, but CE, EE alphabets when used in
same UTF/Unicode databases)

Thanks Matej,

Using a graphic was my "plan B" but I have never used unicodes before 
and thought it would also be handy in other areas where the text content 
might be dynamic.  For example mixing in symbols with some sort of data 
such as someones name.

I'm still curious about the utility of UNICODE2STR() and also how one 
formats the actual unicode to convert it to a string.

In this instance I will likely do as you suggested and resort to graphics.

Thanks for your suggestion... Jonathan

There is an arrow symbol in font Windings chr(232), perhaps you can use 
this ?

Thanks Wolfgang,

But I don't know how I would apply mixed fonts to a push button object 
as I also need to have words.

Jonathan,

As Matej already mentioned, Xbase++ is unable to natively display Unicode 
(UTF-8 or UTF-16) characters with basic XbaseParts and Gra* functions, as 
it uses internally the ANSI API functions. Also, not many fonts actually 
contain that particular Unicode character.

Depending on your use case, you have some other options, though.

For Gra* functions (and XbaseParts with Owner Drawn option), where you can 
switch fonts within a string, I would suggest you stay with an ANSI font and 
use something like this:

Font: "Wingdings"   ==> Character: chr(232)
Font: "Wingdings 3" ==> Character: chr(226)

Both of those fonts should be available to you on most computers. If not, 
you can always look through the fonts that you do have, and find the 
character that best matches your requirements.

For UTF-8 capable Active-X components and the new (but not well documented) 
XbpHTMLWindow()-derived objects, you can indeed use Unicode, though.

And with XbpHTMLStyle() you can draw any HTML/CSS content on a Presentation 
Space. Just specify a Unicode Font that contains this character, like:

[...]
	font-family: "Arial Unicode MS";
[...]

Then your (HTML-encoded) example string to display the arrow would be: 

	"Regular ➔ Banked / OT"

Hope that helps,

Andreas

Hi Andreas... and Thanks for the reminder!

Till did a session on this at SW-Xbase++ in 2015 with a follow-up in 
2016.  I need to review his 2016 white paper & dig into the WebUI 
samples in the 2.0 release.

For now I will use a graphic rendering so it will not depart too much 
from the look/feel of the overall application.

Thanks yet again... always an education Jonathan
