Problems solved by technology

But the problem is that when receiving text stream information, sometimes you don’t know what character set the source text stream is in, so you can’t perform character set conversion

Embodiment Construction

[0056] In the following, the method for determining the text stream character set provided by the present invention will be further specifically described in conjunction with Embodiment 1. Figure 1 is a flowchart of the method.

[0057] In step 101, a character set set is preset, and the character sets in the set are sorted according to the encoding range of the character set, wherein the character set with a small encoding range is arranged first, and the character set with a large encoding range is arranged last.

[0058] In step 102, the first character set in the sequence is set as the current character set, that is, the character set with the smallest encoding range is set as the current character set.

[0059] In step 103, specify the current character set as the source character set of the text stream, and the character set unicode as the destination character set of the text stream, and call the libiconv function library to convert the text stream from the current char...

Abstract

The invention provides a method determining a character set in the text flow, including: default characters in the set, according to the encoding scope of the character set arranging the character set in rank in the pool; Set up the first set of characters in the sequence described for the current character set; convert the above text flow to the character set, if successful conversion, the current characters regarded as the correct source character set in the text flow referred; If the conversion failed, the next step is implemented; judging whether the present character set is the last character set in the sets referred, if not, in the current set up a new character set next to the current set as a new current set, implementing the above step. The present invention also provides a device determining a set of characters in the text flow. Use of methods and devices of this invention providing, can quickly determine a copy of the source of characters in the flow received, at the same time is able to recognize the character sets in the secondary with possible confusion and avoid validation error.

Description

technical field [0001] The invention relates to character detection technology, in particular to a method and device for determining a text stream character set. Background technique [0002] With the development of computer networks and communication technologies, people use the Internet and related electronic services more and more commonly, and information transmission between people with different natural languages ​​in different places through these services is also more and more frequent. [0003] However, users of different languages ​​in different places use different character sets for information processing and transmission stipulated by different countries or regions in their computer devices. Multiple character sets are also used in locales. For example, in China, the character sets used include EUC-CN, HZ, GBK, GB18030, EUC-TW, BIG5, CP950, BIG5-HKSCS, ISO-2022-CN, ISO-2022-CN-EXT, etc.; , the character sets used include ASCII, ISO-8859, KOI8-R, KOI8-U, KOI8-R...
