Artistic Text or paragraph invisible after upgrade to v11 ??

Hi

After we upgrade to Coreldraw 11, we found a problem, some of artistic text or paragraph are disappear after we replace the string thru VBA under some situation.

The string is combination with Chinese Big5 and English character, the strange is when the string is leading by english character followed by chinese then whole artistic or paragraph will become invisiable, but if leading by chinese character, then it appears.

We have same problem on corel draw 10, but we can fix it by applying a style on the string and it works fine , unfortunately, this trick seems not work on coreldraw 11 anymore.

We think it is unicode problem, therefore we use Shape.Text.Story to replace Shape.Text.Contents property, this time the text appear, but all chinese character are scrambled.

Just wonder anyone got solution or answer for it ?

Thank!
