I’ve had a spate of requests recently for the code for Pinyin.info’s tool that converts Chinese characters to Unicode numeric character references<\/a> (i.e., something that converts, say, “漢語拼音” into “&#28450;&#35486;&#25340;&#38899;”). Since I’m a believer in open-source work — and since people could find the code anyway if they look carefully enough in the Web page’s source code — I might as well publish it. <\/p>\n

This tool can be very handy when making Web pages that use a variety of scripts. (It works on Cyrillic, etc., as well.) I often employ it myself. <\/p>\n

Here’s the heart of the code: <\/p>\n


\nfunction convertToEntities() {
\n var tstr = document.form.unicode.value;
\n var bstr = '';
\n for(i=0; i<tstr.length; i++)
\n {
\n if(tstr.charCodeAt(i)>127)
\n {
\n bstr += '&#' + tstr.charCodeAt(i) + ';';
\n }
\n else
\n {
\n bstr += tstr.charAt(i);
\n }
\n }
\n document.form.entity.value = bstr;
\n}<\/code><\/p><\/blockquote>\n

This sleek little bit of Javascript is originally by Steve Minutillo<\/a> and used here on Pinyin.info with his permission. I may have tweaked the code a little myself; but that was so long ago I don’t remember well. (I’ve had the converter here for about five years.) Anyway, if you use this please acknowledge Steve’s authorship; and of course I always greatly appreciate links back to Pinyin.info. <\/p>\n

If anyone knows how to do the same thing in PHP — preferably with no more code than used above, please let me know. <\/p>\n
