Coverting unicode codeepoint format

阅读更多关于 Coverting unicode codeepoint format

问题 Let's say that I have a character string containing bytes representing an emoji: string <- "This is a test. U+1F600" How can I transform it into string <- "This is a test. \U0001F600" So that I can render it as utf8_print("This is a test \U0001F600") [1] "This is a test 😀" 回答1: This is kind of a hack, but it works for your case: string <- c("This is a test. U+1F600", "Another test") # change U+XXXXYYYY to \UXXXXYYYY, quote and encode special characters expr <- gsub("U[+]([0-9A-Fa-f]{1,8})",

Git messes up with non-ascii characters on Linux container

阅读更多关于 Git messes up with non-ascii characters on Linux container

问题 I have a .Net Core (C#) project with the following line in one of the classes: var input = "£"; But when I do a git clone in a Docker container ( microsoft/dotnet:2.2-sdk ) it messes it up and displays it as � (in bash using cat ). And when I run it, its Utf-8 bytes are [239, 191, 189] = [EF, BF, BD] which seem to be a so-called Unicode replacement character. Windows editor that I use is VS 2017, but character is displayed properly on other windows machines and parsed properly by dotnet run

Design decision: Matching cyrillic chars in JSON with PHP

阅读更多关于 Design decision: Matching cyrillic chars in JSON with PHP

问题 I'm developing a plugin for a CMS and have an unanticipated problem: because the plugin is multilang-enabled, input can be of any of the unicode character sets. The plugin saves data in json format, and contains objects with properties value and lookup . For value everything is fine, but the lookup property is used by PHP to retrieve these entities, and at certain points through regexes (content filters). The problems are: For non-latin characters (eg. Экспорт), the \w (word-char) in a regex

Replace a string by character code instead of regex?

阅读更多关于 Replace a string by character code instead of regex?

问题 Does Java (or any other 3rd party lib) provide an API for replacing characters based on character code (within a known Charset of course) rather than a regex? For instance, to replace double quotes with single quotes in a given string, one might use: String noDoubles = containsDoubles.replace("\"", "'"); However the UTF-8 character code for a double quote is U+0022 . So is there anything that could search for instances of U+0022 characters and replace them with single quotes? Also, not just

But if there is diacritic in his/her name, it will be malformed, I tried to set charset in SDK files, but it doesn't help. For example, if the name is René Beneš, it will be RenĂ© BeneĹˇ. Can you help me please? Thank you 回答1: I can describe, at the character level, what is going on here – I hope it helps you closer to a solution. You apparently get the data in UTF-8 encoding, but

Displaying UTF8 stings in Ubuntu's terminal with a Python script

阅读更多关于 Displaying UTF8 stings in Ubuntu's terminal with a Python script

问题 In my Python script running at the command line on Ubuntu, it's selecting UTF8-encoded content from a MySQL database. Then, I want to print the string to the console. The displayed strings have an encoding problem, as they don't show the accented characters correctly. How do I fix this? Preferably, the script would make the decision, rather than setting a system environment, to ensure easy running on other systems. 回答1: It is very strongly recommended that you not use "?" as a replacement
