Code conversion method

Abstract

The present invention relates to a code conversion method. Said method is applicable to portable electronic products, such as handset, etc, with lower arithmetic capability. It is characterized by that said system utilizes ANSI code value of character to make calculation and obtain the offset address of UNICODE code correspondent to said character in UNICODE code table; then utilizes said offset address to find out correspondent UNICODE code in UNICODE code table.

Description

【Technical field】 [0001] The present invention relates to a code conversion method, more specifically, relates to a code conversion method applied to portable electronic products with low computing power. 【Background technique】 [0002] Due to the continuous popularization of mobile phones and the rapid changes in electronic consumer technology, users' requirements for mobile phones are constantly increasing, and the functions of mobile phones are also increasing accordingly. Under this trend, there is the use of reading e-books on mobile phones. The text document on the computer is transferred to the mobile phone for reading. At present, personal computers mainly use the WINDOWS operating system, and the text documents of general users are mostly saved in ANSI encoding format, while ordinary mobile phones can only display characters in UNICODE or UTF-8 encoding format because there is no open operating system.

At present, personal computers mainly use the WINDOWS operating system, and the text documents of general users are mostly saved in ANSI encoding format, while ordinary mobile phones can only display characters in UNICODE or UTF-8 encoding format because there is no open operating system. When it comes to the problem of code conversion, usually the user will perform code conversion on the computer in advance, and then transfer the converted file to the mobile phone, and the conversion between the ANSI code of the character on the computer and the UNICODE or UTF-8 code It is generally done by looking up a table. First, a code conversion table needs to be established in the computer memory. This table is composed of ANSI codes and UNICODE codes corresponding to each character, as shown in the attached figure 2 As shown, the figure provides a part of the table that converts the existing ANSI encoding into UNICODE encoding. The first column is the ANSI encoding sequence, the second column is the UNICODE encoding sequence, and the third column is the corresponding annotation. Then the computer processor converts the ANSI encoding sequence. The code sequence is accessed one by one, and the ANSI code corresponding to the character to be sent to the screen is searched. Only after the ANSI code is found, the corresponding UNICODE code can be obtained. Since this method needs to visit the ANSI code sequence one by one, the amount of calculation generated is relatively large. The computing performance of the computer processor is very high. Using this method to perform code conversion takes a very short time, but the computer processor will not automatically perform the conversion work. Only after proper manual operation, the computer processor will start the code conversion. It is troublesome and not convenient enough to work, but using this code conversion method on the mobile phone, although the above-mentioned manual operation is omitted, but due to the large gap between the computing performance of the mobile phone processor and the computer processor, the conversion speed is slower. Slow, it will take a long time, so adopting a new encoding conversion method, reducing the workload of the mobile phone processor, and improving the efficiency of encoding conversion will bring great convenience to users
