Shift-sensitive variable-width multibyte encoding schemes Some variable-width encoding schemes use control codes to differentiate between single-byte and multibyte characters with the same code values. A shift-out code indicates that the following character is multibyte. A shift-in code indicates that...
The previous, mblen_table-based implementation of mb_substr would treat all of these SJIS-Mac byte sequences as 'one character'. Now, they are treated as multiple characters (one for each of the Unicode codepoints which they decode to). The new behavior is more consistent with other mbstrin...
This document uses the termcharacter setorcharsetto mean a set of rules for mapping from a sequence of bytes to a sequence of characters, such as the combination of a coded character set and a character encoding scheme; this is also what is used as an identifier in MIME "charset=" parame...
EVALUATION The test case in the bug description tests primarily round-trip conversion from Unicode to another encoding and back to Unicode. While it is desirable that such a round-trip conversion results in the original character(s), this can not generally be guaranteed. The anomalies reported by...
In Go Lang, Javascript, NodeJS, PHP 8.0, PHP 7.4 this works correctly. This is quite a BUG and have nothing to do with IConv or MBString. I explain you: $altstr = 'A - B'; // mb detect encoding detects it correctly as UTF-8 $str = 'A + B'; // mb detect encoding detects...
Description:In a nutshell, three other encoding names, Windows-31J, Shift_JIS and MS932 are the aliases for "SJIS" encoding. Connector/J should be able to handle those also when it comes to "characterEncoding" property.How to repeat:Specify one of "Windows-31J", "Shift_JIS" and "MS93...

2.1.4.1 Single-Byte Encoding Schemes Single-byte encoding schemes are efficient. They take up the least amount of space to represent characters and are easy to process and program with because one character can be represented in one byte. Single-byte encoding schemes are classified as one of ...
