How can I use the sequence of the string "\u00e5" in myfile.txt converted unic
How can I use the sequence of the string "\u00e5" in myfile.txt converted to unicode in my application?I have a text file, MyFile.txt, with some sequences represented unicode:
\u00e5
\u00e4
\u00f6
etc.
This is the file contains unicode, not the character it represents: a, a and o.
I get the sequence of the file and save it to a vector. When I tried to use it on a JButton, I see the "\u00e5" string and not the character that I assumed.
read file codes ...
...
Vector<String> glyphVector = readGlyphIndex.getUnicodeFiles(); // to retrieve the vector with unicode sequence and save it to glyphVector
String unicode = glyphVector.get(0); //get the first unicode sequence
System.out.println(unicode); //displays \u00e5 and not å in the console.
jButton.setText(unicode); //jButton is a JButton and it shows the string \00e5 and not the character å
...
The question is how to convert the sequence of string to be a unicode escape in the code?In order to make it clear:
//from
jButton.setText("\\u00e5");
//to
jButton.setText("\u00e5");
Thanks in advance!Dragonfly
String s = Character.toString((char) unicodeInInt);
Strictly speaking, if unicodeInInt is a Unicode code point (for example, it can be greater than 0xFFFF) then the correct code would be this:
String s = new String(Character.toChars(unicodeInInt));
However, since the "\u" notation allows only 4 hexadecimal digits (and need to 0xFFFF code points > Unicode represented by their UTF-16 encoding), the code above is not enough for this particular case.

Can you tell us what steps you took to set your speed dial and use it?
On page 61, you can find information about adding dial numbers to speed up and 62 mentions how you dial. For example if you have saved your Uncle Paul as Dáil speed 3, you simply hold the button 3 to call this contact.

Hello
I have attached here an example of doing the same thing using local variables and shift registers. Take a peek inside. Shift register is always a better option than local variables.

do you mean WiFi Direct or WiDi (wireless display)? If WiDi, you need Intel WiDi software installed on a compatible computer.
What brand of TV and the exact model? If you have Windows Media Center on your computer, you should have Windows Media Player. You can have it disabled in programs, but you can reactivate.

How can I use the DC Acrobat Customization Wizard to include an Adobe ID sign in?
How can I use the DC Acrobat Customization Wizard to include an Adobe ID sign in? I want my users to install through our deployment tools without having to enter an email address and password after launching the software for the first time. Thank you.
This feature has always existed. In the Customization Wizard screen, fill in all fields and don't forget to click on "Grant offline Exception." This avoids having users connect to activate the product because the product is activated by the administrator on behalf of all users.
HTH,

Why are menus grayed out in trial version? How can I use the effects then?
Every piece of software has a learning curve and its own terminology. After Effects is a tool professional complex, used by lovers of the House to feature filmmakers.
There are a lot of video friendly user very editing software that will do the tasks you mentioned easily. I would suggest Adobe Premiere Elements.
For the record, you cannot apply an effect what in After Effects until you have selected a target layer in the timeline panel. This feature is true for any video editing or compositing software I can think,
