Re: ctype_print returns false for British Pound symbol (and non-ASCII symbols)

In which character encoding is your '£' represented? Remember that PHP is ignorant about character encodings, a string is just a sequence of bytes, and it's up to the application developer to make all components agree on the character encoding used. If your '£' happens to be encoded in ISO 8859-1, then its byte representation is the same as "\xA3", which is not a valid UTF-8 string. Norbert On Feb 26, 2010, at 08:21 , Bob wrote:

[I did post this to php.general, but I think php.i18n may be more suitable.] In summary: ctype_print returns false for a string containing the British Pound symbol, and I'm sure that's not how it should behave. So far as I can tell, the British Pound symbol, '£' is considered a printable character according to the locale I use on my Ubuntu box. But even across two years, two boxes, several versions of Ubuntu (from 7.04 to 9.10, one x86, one AMD64), and two major versions of PHP (PHP 4 and now PHP 5.2.11), I cannot get ctype_print to return true when a string given to it contains the British Pound symbol. (Or other non-ASCII characters such as ø or ß.) The locale I'm using is en_GB.UTF-8 and when I call setlocale(LC_ALL, 'en_GB.UTF-8') in PHP, it returns the name of this locale rather than FALSE, so that seems to be in order. (However, to be sure I have installed and reinstalled the language pack in Ubuntu as suggested by others.) I've even read through the en_GB and i18n locale definition files to confirm that <U00A3> (for the British Pound symbol) does appear within the print and graph sections, so both ctype_print and ctype_graph should consider it acceptable. What's most maddening is that ctype_print does return true on my shared hosting server, so I know that it can be achieved. I'm just hoping that someone here can tell me what I'm doing wrong, or what my operating system is doing wrong. For your information, I'm currently running the following: Ubuntu 9.10 (AMD64) Apache 2.2.14 PHP 5.2.11 running as a CGI (to mirror the config of my shared host) Locale in use: en_GB.UTF-8 LANG=en_GB.UTF-8 Can anyone tell me how to get ctype_print to behave? --PHP Unicode & I18N Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
