<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><DIV>I was using the filter to operate on key codes but I never did learn how to get a ASCII character from a UniChar in a decent way. I know I could wrap it into a CFString and convert the character from there, but that's a lot of code for such a simple operation. that snippet seems to accomplish that but i'm not sure what "reinterpret_cast" is. Is there a common utility for this? thanks again.</DIV><BR><DIV><DIV>On Oct 14, 2007, at 8:11 PM, Alfred Van Hoek wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><BR><DIV><DIV>On Oct 14, 2007, at 8:26 AM, Brother Josef wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>It was my understanding that returning false from the text filter hook would prevent WASTE from inserting the character but my callback is not producing these results.
