These systems and methods provide text displays, such as basic input/output system ("BIOS") text displays, that are represented by character strings in string definition files. In order to convert character strings into multiple languages, destination languages are either user selected or predetermined based on the display specifications. Next, the character strings are extracted from the string definition files in a source language into intermediate text files. Each intermediate text file represents a destination language. The source language character strings are then converted to the destination language of each intermediate text file. The converted character strings are then inserted from the intermediate text files into the string definition files from which the character strings in the source language were extracted. A file identifier of each string definition file from which the character strings were extracted is also stored in the intermediate text files. When the converted character strings are inserted into the string definition files, the file identifiers are utilized to locate the string definition files from which the character strings in the source language were extracted.
