This policy setting allows you to restrict character code range of conversion by setting character filter. If you enable this policy setting, then only the character code ranges specified by this policy setting are used for conversion of IME. You can specify multiple ranges by setting a value combined with a bitwise OR of following values: 0x0001 // JIS208 area 0x0002 // NEC special char code 0x0004 // NEC selected IBM extended code 0x0008 // IBM extended code 0x0010 // Half width katakana code 0x0100 // EUDC(GAIJI) 0x0200 // S-JIS unmapped area 0x0400 // Unicode char 0x0800 // surrogate char 0x1000 // IVS char 0xFFFF // no definition. If you disable or do not configure this policy setting, no range of characters are filtered by default. This policy setting applies to Japanese Microsoft IME only. Note: Changes to this setting will not take effect until the user logs off.
