Object names on systems enabled with Japanese language support can contain single-byte Latin and Katakana characters from the JIS X 0201 standard, and double-byte characters from the JIS X 0208 standard.

The valid ranges for JIS X 0201 characters in object names under the KanjiEUC client character set appear in rows cs0 and cs2 in KanjiEUC Code Set Localization. The set does not permit Katakana symbols 0x8EA1—0x8EA5 nor Unicode symbols other than $, #, and _.

The valid ranges for JIS X 0208 characters in object names under the KanjiEUC client character set appear in row cs1 in KanjiEUC Code Set Localization. Characters in the reserved regions of the standard are not allowed.

Characters from JIS X 0212 (row cs3) are not valid in object names. Additionally, some characters that are valid in JIS X 0208 do not map to the KanjiEBCDIC encoding and are not valid in KanjiEUC object names. The following table provides a complete list of multibyte character codes that are not valid for object names under the KANJIEUC_0U character set.

0xA1 0xA1 - 0xAA 0xAD - 0xB1  
0xB3 - 0xBB 0xBD - 0xEF  
0xF1 - 0xF3 0xF5 - 0xFE  
0xA2 0xA1 - 0xFE
