Any Thai character that contains a symbol above it (like an umlat in English) gets corrupted when exporting a report to PDF, yet the same report can be exported to Excel or Word without any issue.
See the following character - once with a symbol above one without:
ล้ ล
The PDF file will not display the first character - instead it displays the second character overlayed on a box (like you get when the font does not contain the required character)
If I create a text field in the Crystal designer, it does the same thing - but when I right click and edit, it displays correctly - until I click out of the field when the problem returns. So this suggests the problem is before the PDF export and maybe with the designer - but then why does it work if i export to Word?
I have tried may different fonts - including those specifically recommended and used by the Thais, but all have the same issue.
My work around at the moment is to use Word instead of PDF, as I do not believe there is a configuration change I can make that will resolve the issue, but would love to hear otherwise.
I am using Crystal Reports for Visual Studio 2010 version 13 running on Windows 7 x64. I have a beta 2 download of v14, but it requires a key code which i do not have, so as yet ahave been unable to verify if this issue is resolved in that version.
if anyone knows otherwise, please let me know
Cheers
