Hello Kohei,<br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
<br>
Just for an idea, we probably should disallow '!' also since we support<br>
Excel A1 and Excel R1C1 formula syntax where '!' is used as the<br>
separator. But we can do that separately.<br>
<div class="im"><br></div></blockquote></div>This is already solved by ScCompiler::IsCharFlagAllConventions. I tested it and it works fine.<br><br>Regards, Markus<br>
