How do I check equality of Unicode strings in Javascript?

问题 I have two strings in Javascript: "_strange_chars_µö¬é@zendesk.com.eml" ( f1 ) and "_strange_chars_µö¬é@zendesk.com.eml" ( f2 ). At first glance, they look identical (and, indeed, on StackOverflow, they may be; I'm not sure what happens when they are pasted into a form like this.) In my application, however, f1[16] // ö f2[16] // o f1[17] // ¬ f2[17] // ̈ That is, where f1 uses the ö character, f2 uses an o and a diacritic ¨ as a separate character. What comparison can I do that will show

Breaking down a Hangul syllable into letters (jamo)

由 元气小坏坏 提交于 2019-12-08 18:23:26
I'm working on a program that deals with Korean sentences and I need a way to break down a syllable, or block, into its letters. For those who don't know Hangul, a syllable is composed of 2-4 letters (jamo), creating thousands of different combinations. What I'd like to do is break down those syllables into the letters that form it. I was able to get the first letter by comparing its Unicode value to the associated letter in that range, i.e. a syllable that starts with x letter is in y range. However, I'm at a loss for finding the rest of the letters. This is a table containing the Unicode

How to handle Combining Diacritical Marks with UnicodeUtils?

问题 I am trying to insert spaces into a string of IPA characters, e.g. to turn ɔ̃wɔ̃tɨ into ɔ̃ w ɔ̃ t ɨ . Using split/join was my first thought: s = ɔ̃w̃ɔtɨ s.split('').join(' ') #=> ̃ ɔ w ̃ ɔ p t ɨ As I discovered by examining the results, letters with diacritics are in fact encoded as two characters. After some research I found the UnicodeUtils module, and used the each_grapheme method: UnicodeUtils.each_grapheme(s) {|g| g + ' '} #=> ɔ ̃w ̃ɔ p t ɨ This worked fine, except for the inverted breve

Is there encoding in Unicode where every “character” is just one code point?

问题 Trying to rephrase: Can you map every combining character combination into one code point? I'm new to Unicode, but it seems to me that there is no encoding, normalization or representation where one character would be one code point in every case in Unicode. Is this correct? Is this true for Basic Multilingual Plane also? 回答1: If you mean one char == one number (ie: where every char is represented by the same number of bytes/words/what-have-you): in UCS-4, each character is represented by a 4

how to extract characters from a Korean string in VBA

由 最后都变了- 提交于 2019-12-06 07:59:32
问题 Need to extract the initial character from a Korean word in MS-Excel and MS-Access. When I use Left("한글",1) it will return the first syllable i.e 한, what I need is the initial character i.e ㅎ . Is there a function to do this? or at least an idiom? If you know how to get the Unicode value from the String I'd be able to work it out from there but I'm sure I'd be reinventing the wheel. (yet again) 回答1: I think what you are looking for is a Byte Array Dim aByte() as byte aByte="한글" should give

If you mean one char == one number (ie: where every char is represented by the same number of bytes/words/what-have-you): in UCS-4, each character is represented by a 4-byte number. That's way more than big enough for every character to be represented by a single value, but

Unicode-ready wordsearch - Question

Is this code OK? I don't really have a clue which normalization-form I should us (the only thing I noticed is with NFD I get a wrong output). #!/usr/local/bin/perl use warnings; use 5.014; use utf8; binmode STDOUT, ':encoding(utf-8)'; use Unicode::Normalize; use Unicode::Collate::Locale; use Unicode::GCString; my $text = "my taxt täxt"; my %hash; while ( $text =~ m/(\p{Alphabetic}+(?:'\p{Alphabetic}+)?)/g ) { #' my $word = $1; my $NFC_word = NFC( $word ); $hash{$NFC_word}++; } my $collator = Unicode::Collate::Locale->new( locale => 'DE' ); for my $word ( $collator->sort( keys %hash ) ) { my

What kind of normalization is used by Swift string comparisons?

由 前提是你 提交于 2019-12-05 06:51:15
Elsewhere I've seen it told that Swift's comparisons use NFD normalization. However, running in the iSwift playground I've found that print("\u{0071}\u{0307}\u{0323}" == "\u{0071}\u{0323}\u{0307}"); gives false , despite this being an example straight from the standard of "Canonical Equivalence", which Swift's documentation claims to follow . So, what kind of canonicalization is performed by Swift, and is this a bug? It seems that this was in bug in Swift that has since been fixed. With Swift 3 and Xcode 8.0, print("\u{0071}\u{0307}\u{0323}" == "\u{0071}\u{0323}\u{0307}") now prints true . 来源：

Unicode string normalization in C/C++

由 余生长醉 提交于 2019-12-04 16:48:50
问题 Am wondering how to normalize strings (containing utf-8/utf-16) in C/C++. In .NET there is a function String.Normalize . I used UTF8-CPP in the past but it does not provide such a function. ICU and Qt provide string normalization but I prefer lightweight solutions. Is there any "lightweight" solution for this? 回答1: As I wrote in another question, utf8proc is a very nice, lightweight, library for basic Unicode functionality, including Unicode string normalization. 回答2: For Windows, there is
