由 感情迁移 提交于 2019-12-24 03:45:05
问题 Is there a way to translate unicode emojis to an appropriate ascii emoticon in Python? I know the emoji library which can be used to convert unicode emojis to something like :crying_face:. But what I would need is to convert it to :'( Is there an elegant way to do this without having to translate every possible emoji manually? Another option would be to convert the ascii emojis also to their textual representation, i.e. :'( should become :crying_face:. My intermediate goal is to find a way to

I can't found any good solution to do it. Let say that i have this string: " xxx 👦🏿 sss 🤖 " How can I get these 2 emojis?

Android Detect Flag Emojis Present

问题 It was my understanding that as of Lollipop (Android 5.0), the flag emojis would be included. I have a Google Nexus device and a Samsung Galaxy Note 4, and the Nexus has the emojis while the Samsung just shows the two letter country code. Is there anyway to detect if the flag emojis are supported so I could just hide the country codes if the emoji flags aren't there? 来源： https://stackoverflow.com/questions/36780166/android-detect-flag-emojis-present

问题 I found this code in Python for removing emojis but it is not working. Can you help with other codes or fix to this? I have observed all my emjois start with \xf but when I try to search for str.startswith("\xf") I get invalid character error. emoji_pattern = r'/[x{1F601}-x{1F64F}]/u' re.sub(emoji_pattern, '', word) Here's the error: Traceback (most recent call last): File "test.py", line 52, in <module> re.sub(emoji_pattern,'',word) File "/usr/lib/python2.7/re.py", line 151, in sub return

问题 I'm trying to display an emoji (ascii #55357) in CoreText and this is what I'm getting: It displays two of these characters and inserts the cursor in the middle. I'm not going to include my CoreText code because it's such a mess and I have no idea where the bug is originating from, but what I was just curious has anyone else seen the same problem before in any facet of iOS and what is the meaning of these sort of A in a black and white box characters that got displayed? Does it mean invalid

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 正则表达式和其在OC中的的使用 最近对正则表达式(regex)很感兴趣, 于是了解了一下, 正则表达式是所有语言都通用的一套查找字符串的方法, 在网上找了很多入门教程, 也看了很多的教程, 也能写出来简单的正则表达式了, 但是好像还是似懂非懂的. 学习正则表达式, 看再多的教程, 都不如自己认认真真的做练习学习的快. 好吧, 我来总结一下, 供自己以后参考: 1. 先贴几个表, 正则表达式经常用到的字符及含义 表一 : 常用的元字符 代码 说明 . 匹配除换行符以外的任意字符 \w 匹配字母,数字,下划线,汉字 \s 匹配任意空白符 \d 匹配数字 \b 匹配单词的开始或者结束 ^ 匹配字符串的开始 $ 匹配字符串的结束 表二 : 常用的限定符 代码 说明 * 重复零次或者更多次 (重复任意次数) ? 重复零次或者一次 (重复次数小于等于1) + 重复一次或者更多次 (重复次数大于1) {n} 重复n次 {n,} 重复次数大于等于n {n, m} 重复n到m次 表三 : 常用的反义代码 代码 说明 \W 匹配任意非 字母,数字,下划线,汉字 \S 匹配任意非 空白符 \D 匹配任意非 数字 \B 匹配任意非 单词的开始或者结束 [^x] 匹配任意除了x外任意字符 [^aeio] 匹配任意非aeio的字符 表四

How to know which Unicode Emoji flags are supported per iOS or Android version?

由 守給你的承諾、 提交于 2019-12-23 19:52:21
问题 Unicode's national flag Emojis are special compared to other Unicode characters and even to other Emoji characters. All Emoji characters are outside the BMP in the "astral" plane of Unicode, which means that the Unicode codepoints are made up of a "surrogate pair", which is two JavaScript "characters" since JS predates UTF-16 when UCS-2 was in use. But the flag Emoji actually require two codepoints, so four JavaScript "characters". I don't know whether this is unique among Unicode characters

Why is Swift counting this Grapheme Cluster as two characters instead of one?

由 此生再无相见时 提交于 2019-12-23 13:08:37
问题 Generally Swift is really smart about counting grapheme clusters as a single character. If I want to make a Lebanese flag, for example, I can combine the two Unicode characters U+1F1F1 REGIONAL INDICATOR SYMBOL LETTER L U+1F1E7 REGIONAL INDICATOR SYMBOL LETTER B and as expected this is one character in Swift: let s = "\u{1f1f1}\u{1f1e7}" assert(s.characters.count == 1) assert(s.utf16.count == 4) assert(s.utf8.count == 8) However, let's say I want to make a Bicyclist emoji of Fitzpatrick Type
