Redis中的事务自动增量ID(ServiceStack RedisClient)(Autoincrement Id with transaction in Redis (ServiceStack RedisClient))
Redis中的事务自动增量ID(ServiceStack RedisClient)(Autoincrement Id with transaction in Redis (ServiceStack RedisClient))
使用IncrementKey的ActionSuccess回调在事务中不起作用:
public class Article { public long Id { get; set; } public string Name { get; set; } } [Test] public void Can_create_article_with_autoincremental-id() { Article a = new Article() { Name = "I Love Writing Test" }; using (var trans = Redis.CreateTransaction()) { trans.QueueCommand(r => r.IncrementValue("id:article"), id => a.Id = id); trans.QueueCommand(r => r.Store<Article>(a)); trans.Commit(); } Assert.That(Redis.Get<Article>("1").Id,Is.Equal("1")); }
ActionSuccess callback with IncrementKey does not work in transaction:
public class Article { public long Id { get; set; } public string Name { get; set; } } [Test] public void Can_create_article_with_autoincremental-id() { Article a = new Article() { Name = "I Love Writing Test" }; using (var trans = Redis.CreateTransaction()) { trans.QueueCommand(r => r.IncrementValue("id:article"), id => a.Id = id); trans.QueueCommand(r => r.Store<Article>(a)); trans.Commit(); } Assert.That(Redis.Get<Article>("1").Id,Is.Equal("1")); }

您可以将编码传递给
Integer#chr
:hex = 0x0905 hex.chr('UTF-8') #=> "अ"
如果
Encoding::default_internal
设置为UTF-8,则可以省略该参数:$ ruby -E UTF-8:UTF-8 -e "p 0x0905.chr" "अ"
您还可以将代码点附加到其他字符串:
'' << hex #=> "अ"
You can pass an encoding to
Integer#chr
:hex = 0x0905 hex.chr('UTF-8') #=> "अ"
The parameter can be omitted, if
Encoding::default_internal
is set to UTF-8:$ ruby -E UTF-8:UTF-8 -e "p 0x0905.chr" "अ"
You can also append codepoints to other strings:
'' << hex #=> "अ"

是否可以在Java中动态生成Unicode字符?(Is it possible to dynamically generate Unicode characters in Java? [duplicate])[2022-02-23]
您可以简单地将代码点值转换为char : (char)0x2070 + x 请注意,您可能会考虑以十六进制表示的代码点值。 You can simply cast the codepoint value to a char: (char)0x2070 + x Note that you probably think about codepoint values in hex. -
如何在Python中替换字符串中的无效unicode字符?(How to replace invalid unicode characters in a string in Python?)[2022-04-09]
如果您有一个bytestring (未解码的数据),请使用'replace'错误处理程序。 例如,如果您的数据(大部分)是UTF-8编码的,那么您可以使用: decoded_unicode = bytestring.decode('utf-8', 'replace') 和U + FFFD REPLACEMENT将为任何无法解码的字节插入字符字符。 如果您想使用不同的替换字符,以后可以轻松替换这些字符: decoded_unicode = decoded_unicode.replace(u'\ufffd', ... -

如果Unicode转义序列完全包含在单个字符串文字中,则它们只能被识别。 连接转义序列的部分将不起作用。 要从代码点动态创建字符串,请尝试String.fromCodePoint 。 该函数将代码点作为数字,而不是字符串。 // works console.log("\u0041"); // doesn't work try { eval('console.log("\\u" + "0041");'); } catch (e) { console.log(e.message); ...
