Does ArcSDE support Welsh characters not found in the standard Windows code page?
Most Welsh alphabet characters are found in the standard Windows code page (WE8MSWIN1252), but some letters, such as all vowels and the letters w and y, can take a circumflex or caret (^) accent. In Welsh, the caret accent is called a 'to bach', meaning 'little roof'. Adding this results in the letters appearing as follows:
ŵ and ŷ
These characters might be stored in Oracle or SQL Server tables, but the characters are being composed using other code pages or Unicode, since they are not supported in the standard Windows code page.
ArcSDE can display all Welsh characters supported in the standard Windows code page (WE8MSWIN1252). However, Welsh characters not in the standard code page(s), which may be composite characters or characters composed using other code pages or Unicode, may not appear with the appropriate caret character in ArcSDE. In the case of these nonstandard characters, they may revert to the non-careted versions or another character, depending on the font being used.
ArcSDE versions prior to ArcSDE 9.2 have no workaround for this issue.
Beginning with the 9.2 release, Unicode characters are supported and rendered as expected.
