Are supplementary characters allowed in XML names?

问题 According to the specification the characters [#x10000-#xEFFFF] are legal in XML names. However, the W3 validator says that this XML is not well-formed: <?xml version="1.0"?> <𐐀>value</𐐀> (the name of the attribute is a Unicode character #x10400). Some browsers, like Firefox, also complain about it (Chrome displays XML, IE shows a blank page). Is it an error in tools or the XML is really not well-formed? 回答1: Is it an error in tools or the XML is really not well-formed? It's well formed in

ODBC connector support for utf8mb4 in MYSQL

问题 I have been stuck up in this scenario. My application is in C++ which connects to MySQL database 5.5.34 through MySQL odbc connector v5.2 Unicode Driver. My tables were using the character set and collation properties 'utf-8'. To insert supplementary unicode characters, i changed it via My table was initially created: CREATE TABLE mytable (SAMPLECOLUMN text) ENGINE=InnoDB DEFAULTCHARSET=utf8; changed to, ALTER TABLE mytable CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; After

Java reading in character streams with supplementary unicode characters

问题 I'm having trouble reading in supplementary unicode characters using Java. I have a file that potentially contains characters in the supplementary set (anything greater than \uFFFF). When I setup my InputStreamReader to read the file using UTF-8 I would expect the read() method to return a single character for each supplementary character, instead it seems to split on the 16 bit threshold. I saw some other questions about basic unicode character streams, but nothing seems to deal with the

Map supplementary Unicode characters to BMP (if possible)

问题 I ran into the issue that my XML parser (VTD-XML) doesn't seem to be able to handle Unicode Supplementary characters (please correct if I'm already wrong here). It seems, the parser only uses the lower 16 bit of such characters. I cannot switch to another parser within the project I'm occupied with. I am parsing Medline abstracts (https://www.ncbi.nlm.nih.gov/pubmed) and it seems there have been added documents that contain supplementary characters over the last year (e.g. https://www.ncbi

UICollectionView Floating Headers on Top and Side

由 亡梦爱人 提交于 2019-12-04 09:35:50
问题 How do you implement headers in a UICollectionView ? I know you can put in supplementary views, but I don't know how to make them "float" above a section like headers in a UITableView do. Here's my situation: I have a collectionView with the cells laid out in a grid format. You can scroll horizontally and vertically. I want to have a header on top so that when you scroll horizontally it scrolls horizontally with it, but it doesn't scroll vertically. I also want the same sort of thing on the

How to make Supplementary View float in UICollectionView as Section Headers do in UITableView plain style

由 爷，独闯天下 提交于 2019-11-26 07:53:42
问题 I\'m struggling to achieve a \"floating section header\" effect with UICollectionView . Something that\'s been easy enough in UITableView (default behavior for UITableViewStylePlain ) seems impossible in UICollectionView without lots of hard work. Am I missing the obvious? Apple provides no documentation on how to achieve this. It seems that one has to subclass UICollectionViewLayout and implement a custom layout just to achieve this effect. This entails quite a bit of work, implementing the
