Unicode: Strings
built 643 days ago
Once you've written some code that works with Unicode data, the next problem is input/output. How do you get Unicode strings into your program, and how do you convert Unicode into a form suitable for storage or transmission?

Who doesn't know what Unicode is? Now that computing has become so widespread and Web-centric -- a revolution in itself -- we are on the brink of another revolution in computing, one that can have profound effects on all of us and perhaps even on the course of history.

Injective mappings must be provided between characters in existing legacy character sets and characters in Unicode to facilitate conversion to Unicode and allow interoperability with legacy software. Lack of consistency in various mappings between earlier Japanese encodings such as Shift-JIS or EUC-JP and Unicode led to round-trip format conversion mismatches, particularly the mapping of the character JIS X 201 '~' (1-33, WAVE DASH), heavily used in legacy database data, to either '~' U+FF5E FULLWIDTH TILDE (in Microsoft Windows) or '〜' U+301C WAVE DASH (other vendors).[18]
With this mechanism, an application can use the generic API function to work transparently with Unicode, depending on the #define UNICODE manifest constant. It can ... make mixed calls by using the explicit function name with "W" or "A."

You can make a connection from a traditional environment to a Unicode platform (such as Plan 9) and have Kermit translate between your local character-set and Unicode during the terminal session. Or vice versa. (3)

The right-click context menu of most controls displaying Unicode mappings contains the item Locate (middle click). Choosing this item, or simply clicking the control with middle mouse button, will cause the Unicode palette to locate (set as current) the character displayed in the control.
