Do search engines understand special/foreign characters?

[TahoeMountain40]

We carry a few brands that have special foreign characters, e.g., Kühl, Lolë, but do search engines recognize special unicode characters? Obviously we would want to spend more energy optimizing keywords that potential customers can type with a keyboard, but is it worthwhile to throw in some encoded keywords and anchor text for people that copy-paste these words into a search?

Do search engines typically equate special characters to their closest English equivalent, or are "Kuhl", "Kühl" and "Kühl" three entirely different terms?

Hi David,

Google/Bing etc. have very few problems recognising such characters in the Latin alphabet. It looks like you are mainly concerned with umlauts, which Google handles intelligently. For example...

• Google will identify the difference between a search for "Küchen" (kitchens in German) and "Kuchen" (cake in German) and offer up relevant results. This is true in Google US and Google UK, not just localised Googles.

• Search suggestions work just fine with these characters, and even with the standardised way of rewriting them when there is no accessible way to type them (for umlauts this is with an e following the letter). For example, in Google.de, type "Kue" and you will be given the suggestion "Küchen".

You are mainly concerned with brands, which muddies the waters a little because many people in English speaking markets won't bother/know how to type the umlauts. However, Google normally handles this well and recognises the intent.

I would recommend you ensure you consistent use the brand name with the foreign characters, as intended. Google/Bing and co. shouldn't have any problems. Which HTML encoding you use is by the by, in my opinion, as long as the characters are rendering correctly.

Thanks Tom.

While it seems that search engines generally handle these characters well I still had to ask because I did two Google searches: One for "lole" and another for "lolë", and I got very different results. On the first search my website came up on SERP page one but on the second one we were nowhere to be found on any of the first 15 pages.

Whats more, every one of the first 10 SERP pages or so contained at least one instance of the character with an accent in the title, description, or within the on-page copy. So it seems that special characters and regular ascii characters are not one in the same, or at least they are not weighted the same.

I do have to agree with you on the fact that most users will not go through the trouble entering Alt codes on their search bars. On the other hand, the fact that we barely register on SERPs for the company's DBA name might be cause for some concern.
