I'm not sure if I understand your question. But did you try this? : yourCharacter = 16r0026 asCharacter Regards. -- View this message in context: http://forum.world.st/Unicode-in-Smalltalk-tp4676821p4676871.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Changing mouse position from Pharo.

iOS supports a mouse cursor if you want to. Jailbroken iDevices have that support w/ BT mice for example. It is just that they don't want us to see it. http://modmyi.com/content/8960-control-your-ios-device-bluetooth-mouse-trac… Furthermore, nothing preclude us from using the last touch for showing a mouse cursor and on screen areas for red/yellow/blue Phil 2013/3/14 Igor Stasenko <siguctua(a)gmail.com>: > On 14 March 2013 20:48, Carla F.

Re: [Pharo-users] Unicode in Smalltalk

by Mohammad Al Houssami (Alumni)

I am trying to build a tokenizer according to the spec below http://www.whatwg.org/specs/web-apps/current-work/multipage/tokenization.ht… Let me take the Data State as an example it says Consume the next input character: U+0026 AMPERSAND (&) Switch to the character reference in data state. So I want to consume the next character of the HTML file and compare it to U+0026. The encoding is probably utf-8 since itâs the most common. The problem is that some characters cannot be written to us the asUnicode function. For example you have these cases which are not trivial: U+0009 CHARACTER TABULATION (tab) U+000A LINE FEED (LF) U+000C FORM FEED (FF) U+0020 SPACE In java you simply do if (c == '\u009'). How does this go in Smalltalk? -----Original Message----- From: pharo-users-bounces(a)lists.gforge.inria.fr [mailto:pharo-users-bounces@lists.gforge.inria.fr] On Behalf Of Igor Stasenko Sent: Thursday, March 14, 2013 8:05 PM To: A friendly place where any question about pharo is welcome Subject: Re: [Pharo-users] Unicode in Smalltalk On 14 March 2013 20:58, Mohammad Al Houssami (Alumni) <mha53(a)mail.aub.edu> wrote: > Hello again. > > > > Does anyone know how can we reflect Unicode characters in Smalltalk? > what you mean reflect? > I want to read characters and compare them with a Unicode representation. > Like U+0026 for & or U+003C for < and so on.. > Piece of cake. $& asUnicode hex '16r26' $< asUnicode hex '16r3C' In Pharo, Character(s) are inherently stored in unicode.

Unicode in Smalltalk

by Mohammad Al Houssami (Alumni)

Hello again. Does anyone know how can we reflect Unicode characters in Smalltalk? I want to read characters and compare them with a Unicode representation. Like U+0026 for & or U+003C for < and so on.. Thanks Mohammad
