Regex - unique vowels considered non-alphanumeric characters

I am facing an issue with RegExp not identifying special characters as word characters (or incorrectly counting them as \b):

"wäww, xöxx  yüyy zßzz".replace(/\b\w/g,function(m){return m.toUpperCase();})

expected result:

"Wäww, Xöxx  Yüyy Zßzz"

current result:

"WäWw, XöXx  YüYy ZßZz"

I have experimented with different encodings but without success...

How can I fix this issue and make it recognize the characters correctly or find a workaround?

A similar problem is discussed in another question on Stack Overflow with no satisfactory solution.

Trick

If you're tired of dealing with the complexities of unicode and JavaScript, consider using a simple space as your indicator for capitalize/replace functions:

> "hello, world".replace(/( |^)[^]/g,function(m){return m.toUpperCase();});
"H ello, W orld"

OR

> "hello, world".replace(/(\s|^)[^]/g,function(m){return m.toUpperCase();});
"H ello, W orld"

OR

> "hello, world".replace(/([\s\.,:;]|^)[^]/g,function(m){return m.toUpperCase();});
"H ello, W orld"

This technique ensures that accented characters are properly capitalized:

> "hello, yes".replace(/( |^)[^ ]/g,function(m){return m.toUpperCase();})
"H ello, Y es"

Answer №2

For those instances where you require it solely for display purposes and not as part of any JavaScript computations, simply apply the CSS style

text-transform: capitalize;

to the specific element will suffice.

Answer №3

My approach to solving the issue was from a different angle: How do I extract the initial letter of every word?

This is the solution I devised:

"wäww, xöxx  yüyy zßzz".replace(/(?:^| )[^ ]/g,function(m){return m.toUpperCase();});

Output:

"Wäww, Xöxx  Yüyy Zßzz"

Answer №4

To make changes to your regular expression, you will need to:

"wäww, xöxx  yüyy zßzz".replace(/[\wäüßö]/g,"x")

Answer №5

To simplify things, you can reverse your statement and specify each non-word character manually (not ideal but practical)

/[^\s,\.;+\- and various other characters]/g

If you are aware of all potential word characters, you could take this approach

/[\wäöüßÄÖÜ and various other characters]/g

Answer №6

When it comes to JavaScript regular expressions, the \w character is used to match Ascii letters, common digits, and underscores only. Essentially, JavaScript regexps operate within the constraints of the Ascii world.

If you find yourself needing to handle a few "special" characters, you can code them individually. However, for a more comprehensive solution, it's recommended to explore libraries that can cater to a wider range of scenarios. This approach is highlighted in responses to the inquiry about Javascript + Unicode regexes, as noted by @Pumbaa80 in a commentary.
