[Kovács Attila]

HI !

I'm new here but I have a problem right at the beginning with the utf8

example :

x="őlma"

see len(x)

see x[1]

result :

alma

5

┼

How can i get the the number of codepoints :?    4

and the first character ? ő

How can i iterate the string ?

Thank you in advance Attila

Hello Attila,

UTF-8 is a specific scheme for mapping a sequence of 1-4 bytes to a number

as seen in

ring/samples/General/Hex2UTF8

If you are using Qt, look for QString class, fromUtf8 and toUtf8 methods

https://doc.qt.io/qt-5/qstring.html#toUtf8

Thanks Ilir !

I'll try them.

Hello Attila

As Ilir said, Check the QString class

Also look at this example: https://github.com/ring-lang/ring/blob/master/samples/UsingArabic/WriteArabicInString/qstring_arabicstring1.ring

Hello Attila:

You can also also use SoftanzaLib like this;

load "stzlib.ring"

o1 = new StzString("őlma")
? o1.NumberOfChars() #--> 4
? o1[1] #--> "ő"

To install the library enter this line in the console:

ringpm install softanzalib from mayouni

PS: Please note that Softanza is in beta now.

Best,

Mansour
