Topic: How to read Unicode

[Jeremy]

We have the ASCII and CHR functions to deal with ASCII codes. VL-STRING->LIST converts a string to a list of Ascii codes. Is there any way to extract Unicode character codes from a string in AutoLISP? I would like a routine that would act like VL-STRING->LIST only that would return Unicode codes.

Perhaps something like attached?

Though note it's loading the entire UniCode data list into RAM - uses just under 10MB for such. Though you'd then be able to convert to UniCode or UTF8 from there.

It's probably not the most efficient way of doing this, but it's a pure AutoLisp way. Thus it "should" work even on ACad for mac / BricsCAD on Linux.

I've been working on a DotNet implementation of this. The attached is the source in C# together with the Debug / Release DLL's - made in Visual Studio 2008. I've tested on ACad 2011/12 thus far. The file read/write routines still have an issue, but the attached converts properly between ASCII/UniCode/UTF7/UTF8/UTF32.

NetLoad one of the DLL's in the folder .\BinaryFiles\bin\Debug or .\BinaryFiles\bin\Release.

Then you should have several new lisp functions to call: string-to-unicode, string-to-ASCII, string-to-UTF7, string-to-UTF8, string-to-UTF32, unicode-to-string, ascii-to-string, UTF7-to-string, UTF8-to-string, UTF32-to-string.
