Probably because the character codes have assigned Unicode numbers lower than а or higher than я.And your regular expression is only seems to be checking lowercase letters.

XHTML 1.0 Strictcharset="utf-8"And ereg() Searches a string for matches to the regular expression given in pattern in a case-sensitive way. eregi() This function is identical to ereg() except that it ignores case distinction when matching alphabetic characters. http://ru2.php.net/function.ereghttp://ru2.php.net/eregi

Even if encoded in UTF-8, the order of the characters is the same as in unicode.I'm checking the character map, there appear to be cyrilic characters beyond я.Try this instead:

[a-zа-ө]

aaaaaa +bbbbbb +AAAAAA +BBBBBB +аааааа + (first rus letter)бббббб + (second rus letter)АААААА - (first upper size rus letter)ББББББ - (second upper size rus letter)йййййй + (rus letter №11)ЙЙЙЙЙЙ - (upper rus letter №11)фффффф - (rus letter)Same Result!

Ive used your "Preview Post" function in "NewTopic"for

a-zа-яA-ZА-Я

and i got same in "Post Preview" box but original code changed to

a-z& # 1072;-& # 1103;A-Z& # 1040;- & # 1071;

with out spaces of course Edited August 4, 2009 by es131245

When you use a range like this:[a-z]It checks the ASCII character set only. If you want to check for Unicode characters you need to give the character codes, not the actual characters. Examples here:http://unicode.org/reports/tr18/

I got some difficulties with unicodenon of those helped ƚ - ,F; U+0410-U+044F \p{Cyrillic}may anyone explain this to me?

It looks like you can use your character ranges as long as you use the UTF modifier. First, don't use ereg functions, they are gone as of PHP6. Use the preg functions instead. Use preg_match to match your string against the pattern, and check the modifiers reference to see how to make it case-insensitive and to turn on UTF mode:http://www.php.net/manual/en/book.pcre.php
