Javascript string comparison fails when comparing unicode characters

由 时光怂恿深爱的人放手 提交于 2019-11-27 04:40:04
I want to compare two strings in JavaScript that are the same, and yet the equality operator == returns false. One string contains a special character (eg. the danish å ). JavaScript code: var filenameFromJS = "Designhåndbog.pdf"; var filenameFromServer = "Designhåndbog.pdf"; print(filenameFromJS == filenameFromServer); // This prints false why? The solution What worked for me is unicode normalization as slevithan pointed out. I forked my original jsfiddle to make a version using the normalization lib suggested by slevithan.

File.listFiles() mangles unicode names with JDK 6 (Unicode Normalization issues)

I'm struggling with a strange file name encoding issue when listing directory contents in Java 6 on both OS X and Linux: the File.listFiles() and related methods seem to return file names in a different encoding than the rest of the system. Note that it is not merely the display of these file names that is causing me problems. I'm mainly interested in doing a comparison of file names with a remote file storage system, so I care more about the content of the name strings than the character encoding used to print output. Here is a program to demonstrate. It creates a file with a Unicode name

php iconv translit for removing accents: not working as excepted?

问题 consider this simple code: echo iconv('UTF-8', 'ASCII//TRANSLIT', 'è'); it prints `e instead of just e do you know what I am doing wrong? nothing changed after adding setlocale setlocale(LC_COLLATE, 'en_US.utf8'); echo iconv('UTF-8', 'ASCII//TRANSLIT', 'è'); 回答1: I have this standard function to return valid url strings without the invalid url characters. The magic seems to be in the line after the //remove unwanted characters comment. This is taken from the Symfony framework documentation:

What is the best way to remove accents with Apache Spark dataframes in PySpark?

问题 I need to delete accents from characters in Spanish and others languages from different datasets. I already did a function based in the code provided in this post that removes special the accents. The problem is that the function is slow because it uses an UDF . I'm just wondering if I can improve the performance of my function to get results in less time, because this is good for small dataframes but not for big ones. Thanks in advance. Here the code, you will be able to run it as it is

How does unicodedata.normalize(form, unistr) work?

由 我们两清 提交于 2019-11-26 14:34:54
问题 On the API doc, http://docs.python.org/2/library/unicodedata.html#unicodedata.normalize. It says Return the normal form form for the Unicode string unistr . Valid values for form are ‘NFC’, ‘NFKC’, ‘NFD’, and ‘NFKD’.` The documentation is rather vague, can someone explain the valid values with some examples? 回答1: I find the documentation pretty clear, but here are a few code examples: from unicodedata import normalize print '%r' % normalize('NFD', u'\u00C7') # decompose: convert Ç to "C + ̧"

What is normalized UTF-8 all about?

由 一笑奈何 提交于 2019-11-26 11:46:07
问题 The ICU project (which also now has a PHP library) contains the classes needed to help normalize UTF-8 strings to make it easier to compare values when searching. However, I\'m trying to figure out what this means for applications. For example, in which cases do I want \"Canonical Equivalence\" instead of \"Compatibility equivalence\", or vis-versa? 回答1: Everything You Never Wanted to Know about Unicode Normalization Canonical Normalization Unicode includes multiple ways to encode some
