String truncation method and device

Abstract

Methods, apparatus, and terminal devices for truncating a character string are provided. A character string to be truncate is read and a byte length occupied by a current character is obtained. It is determined whether a substring, formed from a starting character of the character string to be truncated to the current character, satisfies a pre-set truncating condition. When the substring, formed from the starting character of the character string to be truncated to the current character, satisfies the pre-set truncating condition, the current character is subtracted from the substring to generate a truncated substring for displaying, according to the byte length occupied by the current character.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a string truncation method and device. Background technique [0002] In the interface display of some application programs, due to the limitation of the size and position design of the interface text control, it is often necessary to truncate strings of various lengths before displaying them in the text control. In the prior art, it is common practice to preset the maximum number of bytes for character strings of different lengths, and if the number of bytes contained in the string to be displayed exceeds the preset maximum number of bytes, the characters are truncated String, only display the substring consisting of the largest number of bytes before it, and attach an ellipsis to indicate that the displayed content is a truncated substring if necessary. [0003] However, in some character encoding environments, the number of bytes occupied by Chinese, English or other symboli...
