[racket-users] Using DrRacket interface language with scribble

In DrRacket, if I set interface language to Chinese, I can get > (check-satisfied 1 odd?) 测试通过！ That is, the output of check-satisfied is also in Chinese. But with scribble/eval (https://docs.racket-lang.org/scribble/eval.html), in the .html generated by scribble, I always get > (check-satisfi

Re: [racket] Writing UTF-16 to a socket/file

You can use string->utf16 from rnrs/bytevectors-6: (require rnrs/bytevectors-6) (string->utf16 "abc") and them use "write-bytes". Chongkai On 2/12/2011 2:35 PM, Gregory Woodhouse wrote: Is it possible to ensure that data written to a socket or file is encoded as UTF-16? I ask because Healt

[racket] FFI question: a callback that will be called by some foreign thread

Using FFI, one can use _cprocedure to pass Scheme procedures to foreign functions as C callback. For my case, if the callback function is called from a different C thread (unknow to PLT FFI), it crashes. Adding #:atomic? #t doesn't help. Is there a workaround, or could I conclude that FFI can't
