Visual FoxPro 9.0報告顯示unicode

Question

我正在使用Visual Foxpro 9，我想在報告（frx）中打印Unicode字符。 有一些方法可以擴展報告監聽器以顯示unicode。我需要代碼來擴展/顯示reportListner以顯示unicode。

Answer 1

我從來沒有與任何VFP內的Unicode工作，或者花費任何時間與報告工作，但幫助了ReportListener的的Render方法確實提到的Unicode：

cContentsToBeRendered

Indicates the text to be rendered for Expression (Field) and Label layout elements. 
For Picture layout elements sourced from a file, cContentsToBeRendered contains the filename. 

When specifying a filename for an image, ReportListener provides cContentsToBeRendered 
as a DBCS string, which is the standard format for strings in Visual FoxPro. 
However, when indicating text to be rendered, ReportListener provides 
cContentsToBeRendered as a Unicode string, appropriately translated to the correct 
locale using any regional script information associated with this layout control in 
its report definition file (frx) record. 

If your derived class sends the text value through some additional processing, such as 
storage in a table, you can use the STRCONV() function, and its optional regional 
script parameter, to convert the string to DBCS first. For more information, see 
STRCONV() Function. 

Answer 2

雖然我可能不正確，但我相信VFP不支持UniCode，只能用於基本ASCII字符集。但是再一次，我從來都不需要使用Unicode，並且從使用壽命開始就使用了FoxPro。

我會想像瑞克斯特拉爾的文章Using Unicode in Visual FoxPro Web and Desktop Applications將在這個話題上相當明確。
