Abstract

A management module registers a request to convert code from a first code set to a second code set, identifies a code set converter (CSC), determines whether a most recently used CSC is the identified CSC and, in response to determining that the most recently used CSC is not the identified CSC, locates a user-preferred CSC pool comprising a subset of locally stored CSCs each corresponding to a preference index. The management module, in response to determining that the identified CSC is located within the user-preferred CSC pool, searches the user-preferred CSC pool for the identified CSC, loads the identified CSC, initiates the identified CSC that converts the code from the first code set to the second code set, modifies usage data for the identified CSC, and orders the user-preferred CSC pool based on a preference index for each CSC stored in the CSC pool.

Claims

1. A method for code set conversion, the method comprising:

registering a request to convert an encoded character string from a first code set to a second code set;

identifying a code set converter (CSC) which, when executed, converts the encoded character string from the first code set to the second code set;

determining whether a most recently used CSC is the identified CSC;

in response to determining that the most recently used CSC is not the identified CSC, searching for the identified CSC in a user-preferred CSC pool including a subset of locally stored CSCs each corresponding to a respective preference index; and

in response to determining that the identified CSC is located within the user-preferred CSC pool;

loading the identified CSC;

initiating the identified CSC that converts the encoded character string from the first code set to the second code set;

modifying usage data for the identified CSC; and

ordering the user-preferred CSC pool based on a preference index for each CSC stored in the user-preferred CSC pool.

2. The method of claim 1, further comprising:

in response to determining that the identified CSC is not located within the user-preferred CSC pool, searching for the identified CSC in a CSC store holding all of the locally stored CSCs.

3. The method of claim 1, the method further comprising:

registering modification of the usage data for the identified CSC; and

in response to registering the modification of the usage data for the identified CSC;

calculating the preference index for the identified CSC using the usage data;

in response to determining that the identified CSC is not stored in the user-preferred CSC pool, storing the identified CSC in the user-preferred CSC pool; and

reordering the subset of CSCs stored in the preferred CSC pool based on a preference index for each CSC in the user-preferred CSC pool.

4. The method of claim 1, wherein the user-preferred CSC pool includes the subset of CSCs in a particular order, and wherein searching for the identified CSC comprises searching the user-preferred CSC pool in the particular order.

5. The method of claim 3, wherein modification of the usage data for the identified CSC is registered when the identified CSC is initiated by a second system in a same network as the local system.

6. The method of claim 3, wherein the preference index for a particular CSC is calculated based on at least one factor from the group consisting of usage history, business model, geographical location of the user, user input, default weights of each code set, local system properties, and native code set.

7. The method of claim 6, further comprising:

registering modification of at least one of the at least one of the factors; and

in response to registering the modification of the at least one of the at least one of the factors;

calculating the preference index for each CSC in the preferred CSC pool; and

reordering the subset of CSCs stored in the preferred CSC pool based on a preference index for each CSC in the user-preferred CSC pool.

8. A data processing system for code set conversion, the data processing system comprising:

a processor;

data storage coupled to the processor; and

program code stored within the data storage that, when processed by the processor, causes the data processing system to;

register a request to convert an encoded character string from a first code set to a second code set;

identify a code set converter (CSC) which, when executed, converts the encoded character string from the first code set to the second code set;

determine whether a most recently used CSC is the identified CSC;

in response to determining that the most recently used CSC is not the identified CSC, search for the identified CSC in a user-preferred CSC pool including a subset of locally stored CSCs each corresponding to a respective preference index; and

in response to determining that the identified CSC is located within the user-preferred CSC pool;

load the identified CSC;

initiate the identified CSC that converts the encoded character string from the first code set to the second code set;

modify usage data for the identified CSC; and

order the user-preferred CSC pool based on a preference index for each CSC stored in the user-preferred CSC pool.

9. The system of claim 8, wherein the program code further causes the data processing system to, in response to determining that the identified CSC is not located within the user-preferred CSC pool, search for the identified CSC in a CSC store holding all of the locally stored CSCs.

10. The system of claim 8, wherein the program code further causes the data processing system to:
