What is lc ctype

For instance: grep -i i is not guaranteed to match on I in the user's locale. Improve this answer. In practice, most programs will treat them as opaque data and pass them through as you described. I honestly don't know if that's technically "conformant", but we've seen it in the wild.

AndrewJanke, yes. There has been a lot of discussion on the Austin group mailing list on what the properties of the "C" locale character set would be and the general consensus and that will be clarified in the next spec is that that charset would be single-byte, and encompass the full 8bit range with the properties described here.

In the mean-time, yes there can be some divergence as bug or because the spec is not explicit enough. That's what I meant by 6 byte characters. In Unix semantics, one character is one codepoint. Your more than one codepoint "characters" are more generally referenced as graphem clusters to disambiguate from characters. UlysseBN, that has nothing to do with bash. It's about the locale definition.

See lists. Still in current GNU locales as of glibc 2. Show 6 more comments. What do you mean by default language? Yes, I understand the author can do whatever he likes including not do what it says on the tin.

The thing is. So am I entitled to report a bug against a program if that's not the case? Reporting a bug when the default language is not English will make you seem Show 7 more comments.

GAD3R Edward Shen Edward Shen 4 4 silver badges 8 8 bronze badges. I've seen pre-ANSI documentation, and it didn't have locales. Does anyone know why there is this difference? The US locale will sort as follows: a. C aFilename. H basically ignoring the periods. You might prefer: a. H aFilename. H I certainly do. Pivotal HDB. Catalog and Metadata. Product Version. Sub Component.

Article Detail Symptom Description of the symptoms or problem statement. The HDB initialized with Unicode locale shows the following: 1.

Cause Description of what caused the problem. This is a regression code issue introduced since HDB 2. Resolution What actions can the reader take to resolve or work around the described problem?

A permanent fix has been introduced in HDB 2. Additional Information Additional information such as KB articles, references to the original documentation e. Notice that the above commands specify copying the template0 database. When copying any other database, the encoding and locale settings cannot be changed from those of the source database, because that might result in corrupt data. For more information see Section On older systems it is your responsibility to ensure that you use the encoding expected by the locale you have selected.

A mistake in this area is likely to lead to strange behavior of locale-dependent operations such as sorting. Using this combination of settings is deprecated and may someday be forbidden altogether. PostgreSQL supports automatic character set conversion between server and client for certain character set combinations. PostgreSQL comes with some predefined conversions, as shown in Table To enable automatic character set conversion, you have to tell PostgreSQL the character set encoding you would like to use in the client.

There are several ways to accomplish this:. For example, to change the encoding to SJIS , type:.
