说明了在 POSIX 系统 (Linux,Unix) 上使用 Unicode/UTF
说明了在 POSIX 系统 (Linux,Unix) 上使用 Unicode/UTF-8 所需要的信息. 在将来不远的几年里, Unicode 已经很接近于取代 ASCII 与 Latin-1 编码的位置了. 它不仅允许你处理处理事实上存在于地球上的任何语言文字, 而且提供了一个全面的数学与技术符号集, 因此可以简化科学信息交换.
-Described in the POSIX system (Linux, Unix) required the use of Unicode/UTF-8 information. In the near future several years, Unicode is already very close to replace the ASCII and Latin-1 encoded the location of the. It is not only permit In fact you deal with deal with on Earth exists in any language, but also provides a comprehensive mathematical and technical symbol set, it can simplify the exchange of scientific information.
