Guidelines for selecting a Rational ClearQuest data code page

You must consider a number of factors to select the appropriate data code page for a Rational® ClearQuest® schema repository:
  • The data code page is supported by IBM Rational ClearQuest and has been tested and approved for use with it. These code pages are listed in Supported Rational ClearQuest data code pages.
  • The data code page is supported by the vendor databases that you use for all Rational ClearQuest databases within a single schema repository. You must set the vendor database character set of each user database to match the Rational ClearQuest data code page for its schema repository. For more information, see Vendor database character sets and the Rational ClearQuest data code page.
  • All operating systems that run a Rational ClearQuest application must run one of the supported local character sets (locales).
  • After you set the Rational ClearQuest data code page, users cannot enter characters that are not included in that data code page into the database records. However, characters excluded from the data code page can be entered in a file (such as a word processing document) that is attached to the record.
  • In some cases, a Rational ClearQuest data code page contains a subset of the characters in the corresponding vendor database character set. For example, in Japanese, the eucJP local character set contains the characters for half-width katakana, but the corresponding data code page (60932) does not contain those characters. For a list of characters excluded from each Rational ClearQuest data code page, see Rational ClearQuest character exclusion lists.
  • Rational ClearQuest validates data entered from integrations with other Rational products and with Microsoft Project. For more information, see Rational ClearQuest integrations and data code pages.
  • If you are upgrading to version 7.0, you might need to convert characters in an existing database to match the characters in your preferred data code page. For more information, see How upgrading existing databases can affect the choice of a Rational ClearQuest data code page
