If you look in postman, you will probably see that the Content-Type http header sent by the server is missing the encoding tag. This causes the Dart http client to decode the body as Latin-1 instead of utf-8. There’s a simple workaround: http.Response response = await http.get(‘SOME URL’,headers: {‘Content-Type’: ‘application/json’}); List<dynamic> responseJson = json.decode(utf8.decode(response.bodyBytes));
You could use a unicode character class http://www.regular-expressions.info/unicode.html preg_match(“/\p{Han}+/u”, $utf8_str); This just checks for the presence of at least one chinese character. You might want to expand on this if you want to match the complete string.
The correct way of handling variable DPI settings is not to detect them and adjust your controls’ sizes manually in a switch statement (for starters, there are far more possibilities than those you show in your sample if statement). Instead, you should set the AutoScaleMode property of your form to AutoScaleMode.Dpi and let the framework … Read more

Emoji are now the most common non-BMP characters by far. 😂, otherwise known as U+1F602 FACE WITH TEARS OF JOY, is the most common one on Twitter’s public stream. It occurs more frequently than the tilde!
What you are looking for are Unicode properties. e.g. \p{L} is any kind of letter from any language So a regex to match such a Chinese word could be something like \p{L}+ There are many such properties, for more details see regular-expressions.info Another option is to use the modifier Pattern.UNICODE_CHARACTER_CLASS In Java 7 there is … Read more
The problem is due to some R-Windows special behaviour (using the default system coding / or using some system write functions; I do not know the specifics but the behaviour is actually known) To write text UTF8 encoding on Windows one has to use the useBytes=T options in functions like writeLines or readLines: txt <- … Read more
May be you would find a complete list through the CJK Unicode FAQ (which does include “Chinese, Japanese, and Korean” characters) The “East Asian Script” document does mention: Blocks Containing Han Ideographs Han ideographic characters are found in five main blocks of the Unicode Standard, as shown in Table 12-2 Table 12-2.
