Handle code-set conversion

If your Informix® ESQL/C application executes in an environment in which code-set conversion might occur, check that the application correctly handles the following situations:

• When the application writes simple large objects (TEXT or BYTE data) to the database, it must set the loc_type field in the locator structure loc_t to indicate the type of simple large object that it needs to write.
• When the application writes smart large objects (CLOB or BLOB data) to the database, it uses various large-object file descriptors.
• When the application uses the sqlda structure to describe dynamic SQL statements, it must account for possible size differences in character data.
• When the application has character data that might undergo code-set conversion, you must declare character buffers that can hold the data.
