Ascii Values For Umlauts

Q: How do you match umlauts in perl?

A: By ASCII value if you need to. Besides, why wouldn't the Perl tokenizer accept extended ASCII characters?

A: Or if you want a RegularExpression to match ordinary letters and umlauts, use PosixCharacterClasses?.such as [:alpha:], [:alphanum:], [:upper:] and [:lower:].

Q: What are the AsciiValuesForUmlauts?

A: Here's a fragment that shows one way to do this. First determine the set of upper- and lower-case characters
 require 5.004;
 use locale;
 $lc = join '', grep { uc($_) ne $_ } map { chr($_) } 1..255;
 $uc = join '', grep { lc($_) ne $_ } map { chr($_) } 1..255;
next build a regular expression
 $link = "((?:[$uc][$lc]+){2,})[^$uc$lc];
then
 $text =~ m/$link/;
will match ShldWrk. -- DaveSmith


In MicrosoftWindows, you can type these characters by holding down the <alt> key while typing the numbers on the numeric keypad (Num Lock on). Note: these are in the ISO 8859-1 CharacterSet, which is no longer used on this Wiki as of May 2006. EditHint: The table should be updated for the server's reported UtfEight encoding. See UtfEightValuesForUmlauts.

It might be more stable if Wiki sent out HTML elements, &aacute; &auml; etc
