Ok I see and you want probably to scope it during: [ ] setMousePoisitonTo: or something like that.

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

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').
