The International Organization for Standardization (ISO) has published a subset of ideographic characters, named as International Ideographs Core (IICORE) . The IICORE contains 9,810 characters and it can provide conveniences for day-to-day electronic communication in Chinese on resource-limited devices.
IICORE Comparison Utility accepts an UTF-8 encoded plain text file (including UTF-8 encoded HTML) and then lists out the Chinese characters not included in the IICORE. This Utility can be used by web-masters to compare the Chinese content to be accessed by resource limited devices, such as mobile platforms, against IICORE.
For latest information about products on the support of ISO/IEC 10646, users should refer to the corresponding vendor's web sites for details.
