These APIs can be used for fast direct character conversions: Py_UCS4 Py_UNICODE_TOLOWER(Py_UCS4 ch) Return the character ch converted to lower case. 3.3 版后已移除: This function uses simple case mappings. Py_UCS4 Py_UNICODE_TOUPPER(Py_UCS4 ch) Return the character ch converted to up...
Unicode字符集,“字符集”的意思是:为每一个“字符‘”分配一个唯一的 ID(学名为码位 / 码点 / Code Point); Unicode是国际组织制定的可以容纳世界上所有文字和符号的字符编码方案。目前的Unicode字符分为17组编排,0x0000 至 0x10FFFF,每组称为平面(Plane),而每平面拥有65536个码位,共1114112个。目前常用的...
1. Continue to add common characters to it as requested (and document some guidelines for what characters to support) - [ ] 2. Support all Unicode symbols by official name (e.g. \MUSICAL_SYMBOL_SINGLE_BARLINE) (bad idea) 3. Try to find and adopt a canonical mapping from strings to ...
于是便有人想到搞一套全世界通用的编码规则,Unicode应运而生。 国际标准化组织(ISO),他们于1984年创建了工作组,试图制定一份“通用字符集”(Universal Character Set,简称UCS),并制定了ISO 10646标准。统一码联盟,由Xerox、Apple等软件制造商于1988年成立,并且开发了Unicode标准(The Unicode Standard)。 比如"中"字...

Oracle users, refer to theOracle manualfor details on how to set (section 2) or alter (section 11) the database character set encoding. SQLite users, there is nothing you need to do. SQLite always uses UTF-8 for internal encoding. ...
BD1. 双向字符类型是分配给每个Unicode字符的值,包括未被赋值的字符。在Unicode字符数据库[UCD](Unicode Character Database)中,正式的属性名是Bidi_Class。 BD2. 嵌入等级使用数字表示,数字的大小表明文本嵌套的深度,以及表明在该等级上文本的默认方向。文本的最小嵌入等级是0,最大显式深度是125,125作为max_depth...
