Abstract

A computer implemented method, computer program product, and computer system for viewing content encoded in at least one code set and stored in a file system. A computer identifies a unified code set covering all characters used in the file system. The computer, responsive to a user input to view the content, determines whether the content is wholly encoded in the unified code set. The computer, responsive to determining that the code set is not wholly encoded in the unified code set, converts encoding of the content to the unified code set to form converted content. The computer displays the converted content.

Claims

1. A computer implemented method for viewing content encoded in at least one code set and stored in a file system, the computer implemented method comprising:

a computer identifying a unified code set covering all characters used in the file system;

the computer, responsive to a user input to view the content, determining whether the content is wholly encoded in the unified code set;

the computer, responsive to determining that the content is not wholly encoded in the unified code set, converting encoding of the content to the unified code set to form converted content; and

the computer displaying the converted content.

2. The computer implemented method of claim 1, wherein the content comprises file content.

3. The computer implemented method of claim 1, wherein the user input comprises user input to open the content.

4. The computer implemented method of claim 1, wherein the content comprises a file name.

5. The computer implemented method of claim 1, wherein the unified code set is the Unicode code set, and wherein the computer implemented method further comprises saving the converted content to memory.

6. The computer implemented method of claim 1, wherein the unified code set is the Unicode code set, and wherein the computer converting encoding of the content from the code set comprises converting a subset of all content to the Unicode code set.

7. The computer implemented method of claim 5, wherein the computer displaying the converted content comprises the computer displaying the converted content from memory.

8. The computer implemented method of claim 7, wherein the memory is a volatile memory.

9. A computer program product for viewing content encoded in at least one code set and stored in a file system, the computer program product comprising:

one or more computer-readable, tangible storage devices;

program instructions, stored on at least one of the one or more storage devices, to identify a unified code set covering all characters used in the file system;

program instructions, stored on at least one of the one or more storage devices, responsive to a user input to view the content, to determine whether the content is wholly encoded in the unified code set;

program instructions, stored on at least one of the one or more storage devices, responsive to determining that the content is not wholly encoded in the unified code set, to convert encoding of the content to the unified code set to form converted content; and

program instructions, stored on at least one of the one or more storage devices, to display the converted content.

10. The computer program product of claim 9, wherein the content comprises file content.

11. The computer program product of claim 9, wherein the user input comprises user input to open the content.

12. The computer program product of claim 9, wherein the content comprises a file name.

13. The computer program product of claim 9, wherein the unified code set is the Unicode code set, and wherein the computer program product further comprises program instructions, stored on at least one of the one or more storage devices, to save the converted content to memory.

14. The computer program product of claim 9, wherein the unified code set is the Unicode code set, and wherein the program instructions to convert encoding of the content to the unified code set to form converted content comprise program instructions, stored on at least one of the one or more storage devices, to convert encoding of a subset of the content to the Unicode code set.

15. The computer program product of claim 13, wherein the program instructions to display the converted content comprise program instructions, stored on at least one of the one or more storage devices, to display the converted content from memory.

16. The computer program product of claim 15, wherein the memory is a volatile memory.

17. A computer system for viewing content encoded in at least one code set and stored in a file system, the computer system comprising:

one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices;

program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to identify a unified code set covering all characters used in the file system;

program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, responsive to a user input to view the content, to determine whether the content is wholly encoded in the unified code set;

program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, responsive to determining that the content is not wholly encoded in the unified code set, to convert encoding of the content to the unified code set to form converted content; and

program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to display the converted content.

18. The computer system of claim 17, wherein the content comprises file content.

19. The computer system of claim 17, wherein the user input comprises user input to open the content.

20. The computer system of claim 17, wherein the content comprises a file name.

21. The computer system of claim 17, wherein the unified code set is the Unicode code set, and wherein the computer system further comprises program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to save the converted content to memory.

22. The computer system of claim 17, wherein the unified code set is the Unicode code set, and wherein the program instructions to convert encoding of the content to the unified code set to form converted content comprise program instructions, program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to convert encoding of a subset of the content to the Unicode code set.

23. The computer system of claim 21, wherein the program instructions to display the converted content comprise program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to display the converted content from memory.

24. The computer system of claim 23, wherein the memory is a volatile memory.

25. A computer implemented method for use with a file system having files containing multiple code sets to allow viewing of file content encoded in the multiple code sets comprising:

identifying a unified code set covering all characters used in the file system;

detecting at least one code set used with each file name of a folder having a subset of the files, wherein each file is in at least one directory of the file system;

saving, for each file of the folder, the at least one code set in a list to form a corresponding at least one code set for each file;

receiving a user input to open the folder;

responsive to the user input, determining whether a file name corresponding to a folder selected by the user input is encoded in the unified code set;

responsive to a determination that the file name corresponding to the user input is not encoded in the unified code set, determining the at least one character encoding stored with the file name;

responsive to determining the at least one character encoding stored with the file name, converting file name to the unified code set based on the at least one code set to form a converted file name; and

displaying at least the converted file name.
