How to match Cyrillic characters with a regular ex

Question

How do I match French and Russian Cyrillic alphabet characters with a regular expression? I only want to do the alpha characters, no numbers or special characters. Right now I have

[A-Za-z]

Answer 1

It depends on your regex flavor. If it supports Unicode character classes (like .NET, for instance), \p{L} matches a letter character (in any character set).

Answer 2

If your regex flavour supports Unicode blocks, you can match Russian (Cyrillic) characters with:

[\p{IsCyrillic}]

Otherwise try:

[U+0400–U+04FF]

Explanation:

[\p{IsCyrillic}]

Options: Case insensitive; Exact spacing; Dot doesn’t match line breaks; ^$ don’t match at line breaks; Numbered capture

Match a character from the Unicode block “Cyrillic” (U+0400–U+04FF) «[\p{IsCyrillic}]»

Answer 3

To match only Russian Cyrillic characters use:

[\u0401\u0451\u0410-\u044f]

which is the equivalent of:

[ЁёА-я]

where А is Cyrillic, not Latin. (Despite looking the same they have different codes)

\p{IsCyrillic}, \p{Cyrillic}, [\u0400-\u04FF] which others suggested will match all variants of Cyrillic, not only Russian

Answer 4

this worked for me

[a-z\u0400-\u04FF]

Answer 5

If you use modern PHP version - just:

preg_match("/^[\p{L}]+$/u");

Don't forget the u flag for unicode support!

Answer 6

Regex to match cyrillic alphabets with normal(english) alphabets :

^[A-Za-z.!@?#"$%&:;() *\+,\/;\-=[\\\]\^_{|}<>\u0400-\u04FF]*$

It matches special chars,cyrillic alphabets,english alphabets.
