1. Japanese Records and Whether or not to Switch from MARC 8 to Unicode Storage (with an Innovative Interfaces Millennium local system) The University of Washington Law Librarys Decision-making Process

2. Differences in Storage and/or Export Settings With Different Local Systems Your Mileage May Vary Its important to note that different local systems vary widely in whether and how data is stored, imported and exported. These differences will have a huge impact on the experience of librarians making decisions on whether or not to export records in Unicode from OCLC to the local system.

These differences will have a huge impact on the experience of librarians making decisions on whether or not to export records in Unicode from OCLC to the local system. Innovative Interfaces Millennium Local Systems Do not allow import of records encoded differently than the encoding for storage. In other words, If III storage is set to Unicode, records must be imported from OCLC in Unicode.

If storage is set to MARC 8, records must be imported in MARC 8 Voyager Local Systems (CJK version) Can be set to convert imported MARC 8 records to Unicode on-the-fly for storage.

Local systems that store data in MARC 8 cannot import and display Unicode records unless they convert the records to MARC 8. Conversely, local systems storing data in Unicode cannot import MARC 8 records unless the data is converted to Unicode. Ask these questions about your local system: Other Local Systems? Local systems that store data in MARC 8 cannot import and display Unicode records unless they convert the records to MARC 8. Conversely, local systems storing data in Unicode cannot import MARC 8 records unless the data is converted to Unicode. Ask these questions about your local system: What encoding is used for storage?

If not, are imported records automatically converted to the appropriate encoding for storage? If not, are imported records automatically converted to the appropriate encoding for storage?

4. Unicode VS MARC 8 Basics Computers store text as numeric codes. Unicode has become the standard for text storage worldwide. Its use facilitates the storage, transfer, and display of text in a wide range of computer software environments (the internet, databases, browsers, word processors, etc) Computers store text as numeric codes. Unicode has become the standard for text storage worldwide. Its use facilitates the storage, transfer, and display of text in a wide range of computer software environments (the internet, databases, browsers, word processors, etc) What is MARC 8? MARC 8 has been the North American Library Communitys text storage standard. ( The group of 7/8-bit and 24-bit character sets used to encode MARC 21 records. These sets are specified in MARC 21 Specifications for Record Structure, Character Sets, and Exchange Media, Character Sets, Part 1. 1) What is MARC 8?

5. What Problems are Specific to Japanese? Q: Do Some Problems associated with Unicode vs MARC 8 storage affect one language (such as Japanese) more than others? A: Not Really. Problems with character display for specific languages are more often an issue of font availability. Each application must have access to a font that will display the proper characters. Arial Unicode MS can display most Unicode characters. In library records, an additional issue is converting between MARC 8 and Unicode. But these issues can affect many languages and scripts; not just Japanese.

6. What Problems are Specific to Japanese? Q: So are there any Japanese-specific problems? A: Not when it comes to Unicode storage itself. But there are common problems with display of Kanji and Japanese romanization in library catalogs. These are mainly font-availability issues, not Unicode storage issues. Examples of Font-based Problems Specific to Japanese Romanization (Diacritic Problem) Romanization (Diacritic Problem) Alif as in koninAlif as in konin Kanji Examples of Japanese Kanji not in EACC (Different Unicode Code Point Required for Verified Catalog Record in OCLC) Kanji Examples of Japanese Kanji not in EACC (Different Unicode Code Point Required for Verified Catalog Record in OCLC) MARC 8/ EACC: (U+8AAA) instead of (U+8AAC)MARC 8/ EACC: (U+8AAA) instead of (U+8AAC) MARC 8/ EACC: (U+865B) instead of (U+865A)MARC 8/ EACC: (U+865B) instead of (U+865A) MARC 8/ EACC: (U+5377) instead of (U+5DFB)MARC 8/ EACC: (U+5377) instead of (U+5DFB) MARC 8/ EACC: (U+9304) instead of (U+9332)MARC 8/ EACC: (U+9304) instead of (U+9332) MARC 8/ EACC: (U+67E5) instead of (U+67FB)MARC 8/ EACC: (U+67E5) instead of (U+67FB)

7. What Problems are Specific to Japanese? Why Switch to Unicode Storage? Q: If there are no problems with MARC 8 storage specific to Japanese, then why should our library switch to Unicode storage? A: Consider this quote from Microsoft: Deciding whether to store non-DBCS [double- byte character set] data as Unicode is generally determined by an awareness of the effects on storage, and about how much sorting, conversion, and possible data corruption might happen during client interactions with the data... However, for most applications the effect is negligible. Databases with well-designed indexes are especially unlikely to be affected…Deciding whether to store non-DBCS [double- byte character set] data as Unicode is generally determined by an awareness of the effects on storage, and about how much sorting, conversion, and possible data corruption might happen during client interactions with the data...

8. What Problems are Specific to Japanese? Why Switch to Unicode Storage? A: (continued) Most of the time, the decision to store character data, even non-DBCS data, in Unicode should be based more on business needs instead of performance. In a global economy that is encouraged by rapid growth in Internet traffic, it is becoming more important than ever to support client computers that are running different locales. Additionally, it is becoming increasingly difficult to pick a single code page that supports all the characters required by a worldwide audience. 2 2 See the Microsoft article Storage and Performance Effects of Unicode : http://msdn2.microsoft.com/en- us/library/ms189617.aspx http://msdn2.microsoft.com/en- us/library/ms189617.aspxhttp://msdn2.microsoft.com/en- us/library/ms189617.aspx
