I indexed the paragraphes I wrote about Unicode, so you can have quick look: <a class="moz-txt-link-freetext" href="https://cuis-smalltalk.github.io/TheCuisBook/Indexes.html#Indexes_cp_letter-U">https://cuis-smalltalk.github.io/TheCuisBook/Indexes.html#Indexes_cp_letter-U</a> Best Hilaire <div class="moz-cite-prefix">Le 22/02/2023 à 20:10, Juan Vuletich a écrit : </div> <blockquote type="cite" cite="mid:63F668A9.5020005@cuis.st">An important note is that we can make UnicodeString modifiable via #at:put: if we want. In most systems Unicode strings can not be modified. But in Cuis we can compute and store the new 'bytes', nil 'hash' and we are done. On one hand, the system works well with immutable strings. It is not really needed. On the other hand, making them modifiable improves compatibility with older code and tutorials, and other dialects. It is also a good example of Smalltalk "magic". Hilaire, after we make our minds wrt immutable or mutable UnicodeStrings, I'd like to rewrite those sections on the book. In last year's Smalltalks conference at Buenos Aires, I presented a short paper on Unicode in Cuis: <a class="moz-txt-link-freetext" href="https://openreview.net/pdf?id=c93fukpVINA" moz-do-not-send="true">https://openreview.net/pdf?id=c93fukpVINA</a> . The main point I make is that most programmers usually don't need to know or care about the encoding used for Strings. They should only care about their behavior. So, I'd like to rewrite those parts in the same spirit. </blockquote> <pre class="moz-signature" cols="72">-- GNU Dr. Geo <a class="moz-txt-link-freetext" href="http://drgeo.eu">http://drgeo.eu</a> <a class="moz-txt-link-freetext" href="http://blog.drgeo.eu">http://blog.drgeo.eu</a></pre> </body> </html>
