ElevateDB Unicode |
Sat, Mar 11 2006 2:04 AM | Permanent Link |
"Surjanto" | Hi,
May I know what kind of unicode will be supported by ElevateDB ? UCS-2, UTF-16 or UTF-8 ? Will it support Unicode Queries and searching ? I need Unicode and Full Text Search in Unicode. And any prediction when it will be released ? Regards, Surjanto |

<< May I know what kind of unicode will be supported by ElevateDB ? UCS-2, UTF-16 or UTF-8 ? >> Tim has previously mentioned only UCS-2 support, in other words no specific support for the surrogate pairs in UTF-16. I'd really like to see UTF-8 support as well, but that requires a variable number of bytes per Unicode character. I can guess that we might have to wait for UTF-8 in a subsequent release. << And any prediction when it will be released ? >> All you'll ever get from Tim is "when it's ready". Regards, Dan |

"Surjanto" | Dan,
I will need it for Chinese language, does it mean that I can not use ElevateDB for this ? Thanks, Surjanto |

Dan Rootham | Surjanto,
<< I will need it for Chinese language, does it mean that I can not use ElevateDB for this ? >> On the contrary, the use of UCS-2 in ElevateDB ver 5 will make it much easier to handle multiple languages. In particular the use of Unicode will enable us as developers to make applications displaying 2, 3 or more languages at the same time. The only part not covered by ver 5 (as far as I know) is the handling of "surrogate pairs". This is a requirement for full UTF-16 compliance, and it covers some rarely-used characters which are outside the Unicode BMP (basic multilingual plane). As far as I'm concerned, we can do everything we need in our dictionary applications using only the characters contained in the Unicode BMP. No doubt Tim can comment in more detail as the release date gets nearer... Regards, Dan |

<< May I know what kind of unicode will be supported by ElevateDB ? UCS-2, UTF-16 or UTF-8 ? >> UCS-2. Also, there will be separate ANSI and Unicode versions so those that don't want the extra space consumption, etc. with Unicode won't need to use it, but those that do can use it. However, you won't be able to use a Unicode version to access an ANSI database or vice-versa. << Will it support Unicode Queries and searching ? >> Yes. << And any prediction when it will be released ? >> I won't discuss the release date until it's ready. -- Tim Young Elevate Software www.elevatesoft.com |

Do I understand you correctly, that depending on the version of server varchar fields will either be varchar or nvarchar? Michael |

And eventually even the ANSI stuff will be gone in favor of all-Unicode. -- Tim Young Elevate Software www.elevatesoft.com |

Dan Rootham | Tim,
<< And eventually even the ANSI stuff will be gone in favor of all-Unicode. >> I think that many of us have been well and truly confused about Unicode and its various representations. One of the best descriptions I have found is on the Microsoft Internationalization website on a page titled ""Supplementary Characters, Surrogate Pairs and SQL": http://www.microsoft.com/globaldev/DrIntl/columns/021/default.mspx#ECAA I hope this helps others as much as it helped me, at least in terms of defining UCS-2, UTF-8, UTF-16 and UTF-32. (The parts about SQL Server and its SQL are less useful for a DBISAM newsgroup!) Regards, Dan |
