A method and device for compressing a text string into a compressed string, taking into account case sensitivity of the text string. Compression can be performed in lossy mode or lossless mode. In lossy mode, the text string is parsed to determine its case sensitivity so that a search for finding a match for the text string in a reference source is based on the case sensitivity. Alternatively, the case configuration of the characters in the text string is transformed into a target case, and a case-sensitive search is performed to find a match for the case-transformed text string. In lossless mode, a case-insensitive search is performed for finding a match for the text string regardless of its case sensitivity, and a case-info-element is attached to the compressed string so that the compressed string can be reconstructed based on the case-info-element. |
