|
|---|
| 162 | useless:
|
|---|
| 163 | - It returns the empty string when LANG is set to a locale of the
|
|---|
| 164 | form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
|
|---|
| 165 | LC_CTYPE file.
|
|---|
| 166 | - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
|
|---|
| 167 | the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
|
|---|
| 168 | - The documentation says:
|
|---|
| 169 | "... all code that calls BSD system routines should ensure
|
|---|
| 170 | that the const *char parameters of these routines are in UTF-8
|
|---|
| 171 | encoding. All BSD system functions expect their string
|
|---|
| 172 | parameters to be in UTF-8 encoding and nothing else."
|
|---|
| 173 | It also says
|
|---|
| 174 | "An additional caveat is that string parameters for files,
|
|---|
| 175 | paths, and other file-system entities must be in canonical
|
|---|
| 176 | UTF-8. In a canonical UTF-8 Unicode string, all decomposable
|
|---|
| 177 | characters are decomposed ..."
|
|---|
| 178 | but this is not true: You can pass non-decomposed UTF-8 strings
|
|---|
| 179 | to file system functions, and it is the OS which will convert
|
|---|
| 180 | them to decomposed UTF-8 before accessing the file system.
|
|---|
| 181 | - The Apple Terminal application displays UTF-8 by default.
|
|---|
| 182 | - However, other applications are free to use different encodings:
|
|---|
| 183 | - xterm uses ISO-8859-1 by default.
|
|---|
| 184 | - TextEdit uses MacRoman by default.
|
|---|
| 185 | We prefer UTF-8 over decomposed UTF-8-MAC because one should
|
|---|
| 186 | minimize the use of decomposed Unicode. Unfortunately, through the
|
|---|
| 187 | Darwin file system, decomposed UTF-8 strings are leaked into user
|
|---|
| 188 | space nevertheless.
|
|---|
| 189 | Then there are also the locales with encodings other than US-ASCII
|
|---|
| 190 | and UTF-8. These locales can be occasionally useful to users (e.g.
|
|---|
| 191 | when grepping through ISO-8859-1 encoded text files), when all their
|
|---|
| 192 | file names are in US-ASCII.
