I am using RAD Text box.I want to check that if user is entering the value in text box it should only character allow spacing its OK. This can restrict the user to input only characters, but you still have to consider that user can paste.

I am so grateful for this hint! Many Japanese systems can only read ISO-2022-JP messages. I received a few complaints recently about mojibake'd emails that I'd sent, an effect of Mail using UTF-8 for everything. Now I can fix the problem.

How can you set a specific encoding as the DEFAULT encoding in Mail?

open Terminal and type:
[code]defaults write com.apple.mail NSPreferredMailCharset 'ISO-2022-JP' [/code]

open Terminal and type:

So relieved to hear there's a solution. But please forgive me for being an idiot..
What do I do after I open Terminal? I paste in the command you mentioned, and..
Do I save? Where to and what as? What save options do I choose in the dialogue?
Thanks!!

Terminal is located in /Applications/Utilities

After entering (or pasting) that line of text, you just hit return - things you type in the terminal are 'commands' that are executed immediately. There will be no confirmation or alert if it worked.
Saving, in the Terminal application, means either saving a session, or a log of a session's activity, neither of which need to be done for the command to have effect.

Thanks a lot for posting the hint! It, of course, applies to the incoming messages, too -- sometimes the sender does not set the encoding properly and Mail.app incorrectly guesses that it is Western. Use this hint to get more options in the Message -> Text Encoding menu. Also, in case anyone wonders, this hint applies to Tiger Mail just the same.

There is no single default. Mail.app chooses the simplest encoding that accommodates the text you have typed.
So, if you type 'good day', Mail uses US-ASCII. If you type 'good • day' (the Option+8 bullet character between the words), then Mail.app uses 'WINDOWS-1252'. If you type a Japanese character, you are likely to get a Japanese specific charset.
You *can* override that choice of a fancier charset. For example, I want to use UTF-8 instead of 'WINDOWS-1252' or any number of other charsets. I need to add a property to the com.apple.mail.plist file. Do this in either of 2 ways, via the command line or using the GUI program 'Property List Editor' bundled with the 1 gig download of Apple's Xcode Developer Tools from:
http://developer.apple.com/tools/
On the command line in Terminal, type:
defaults write com.apple.mail NSPreferredMailCharset 'UTF-8'
Make a back up copy of com.apple.mail.plist first. I found mine at:
/Users/your_user_name/Library/Preferences/com.apple.mail.plist
Now when you send a message with 'good • day', the message will be in UTF-8. However, if you type 'good day', Mail.app will use US-ASCII. Mail.app is biased towards US-ASCII because that is one of the simplest and most common encodings (Latin-1 and Unicode/UTF-8 are supersets of US-ASCII). Once you add the bullet, Mail needs a fancier encoding, but now it will choose UTF-8 rather than something else.
The info above is based on my own experiments in Mail.app Version 2.1.1 (752.3) bundled with Mac OS X 10.4.8. I simply sent messages to myself with and without the changed plist. To see the encoding of a message, choose View > Message > Raw Source. Then look for the word 'charset'.

When composing word processing documents, or otherwise handling text on your Mac, you might find yourself needing to use special symbols, be it something simple like a star, bullet, or check, or perhaps something more unique like a math symbol or foreign language character. To provide you with this, OS X supports a full set of unicode fonts, and if special characters are needed then there are a couple of quick ways to access and manage them.

The central location for such characters are Apple’s Character Viewer panel; however, Apple has classically made a number of these characters available on the keyboard when using combinations of modifier keys. You can see these by opening a TextEdit document, then holding the Option key while pressing other alphanumeric and punctuation characters.

Holding the Option key with the keyboard viewer open will show the alternative characters you can enter.

Memorizing which key corresponds to a specific character might be a bit of a chore, so to help you can use Apple’s keyboard viewer panel:

  1. Go to the Keyboard tab in the Keyboard system preferences
  2. Check the “Show Keyboard & Character Viewers in menu bar” option
  3. Access the new menu on the right-hand side of the menu bar
  4. Select the “Keyboard Viewer” option
Redshift remove non ascii charactersWhen you do this, a panel representing your current keyboard layout will appear, showing you which characters will be entered when you press the corresponding key on your keyboard. Now if you press and hold various modifier key combinations (Shift, Control, Option, etc.), you will see the keyboard viewer change to show the new characters that are represented by each key with this modifier pressed.

One convenient use of this is to add accents to vowels and other characters that support them. For example, to add a diaeresis (two dots) over the letter “u,” you can first type Option-U to input the diaeresis, followed by typing the “u” letter (or any other that supports the diaeresis) to input that modified letter. The same goes for acute, grave, circumflex, and other accents.

While the keyboard viewer will show you a number of pre-defined alternative symbols, the main source for such symbols is the Character Viewer panel, which can be found in this same menu, or optionally invoked by pressing Option-Command-T in applications that allow this hotkey.

Additional categories can be added to the character viewer using the small gear menu. Canon dr-2510m driver 1.1 for mac.

Similar to the keyboard viewer, the Character Viewer shows in a separate panel, but will give you access to all unicode characters, and offers them in a fairly organized list of categories.

When you first open the Character viewer, you will see only a few of the more common categories, but you can enable others by clicking on the gear menu and choosing “Customize List,” followed by checking the box next to the character categories you want to add.

In addition to browsing for various characters and symbols, you can also search for them by name. For instance, if you know you want to find the specific “cylindricity” technical symbol, then while you locate the “Technical Symbols” category and browse for it, you can simply search for the name. Doing so will show the typed characters of the name you enter, but also any symbols who’s name match the entered search term.

Final conveniences of the character viewer include the Recently Used and Favorites category sections, where you can access the symbols that you regularly use.

The character viewer can also be used for accessing some very uncommon characters as well. For instance, a specific situation would be to replace group separator symbols in a CSV file with a hidden ASCII group separator, such as ASCII character ^29, so the file will properly import into a database or other application you are using. To do this, you can open the CSV in TextWrangler and then use the “Find/Replace” function to search for the current separator character, and then activate the Unicode code table category in the Character Viewer, followed by locating and dragging the ASCII character ^29 to the “Replace” field to swap out these characters.

While this is a specific example, other text-handling routines like this can be performed by similarly using the Character Viewer with a program like TextWrangler.
