C++ regex need to match names containing diacritics

I need to match two word names like (Johny Cash). So I was using the regex:

L"^[A-Z][a-z]+\\s+[A-Z][a-z]+$"

However, I realized that the names may contain diacritics as well, something like Johannes Fürnkranz. I came across following solution and modified my regex to:

L"^[A-Z].\\p{L}+\\s+[A-Z].\\p{L}+$"

This, assuming that the first letter in each word won't be a diacritic. However, I am getting an invalid regex error. Any idea how to make it work?

Following a suggestion, I tried the solution mentioned here. Problem is, the function test_unicode() never returns from me, when I am trying here. Not sure what I am doing wrong.

Use Boost, then you will be able to use `\p{L}` – Wiktor Stribiżew Jan 23 '18 at 18:49
Can't, am stuck to STL regex. :'( – SexyBeast Jan 23 '18 at 18:59

Don't use Boost. Instead of `\\pL` use `[[:alpha:]]+` – rustyx Jan 23 '18 at 19:00
Nope, doesn't work even with that.. – SexyBeast Jan 23 '18 at 19:01

I am trying it on cpp.sh website. What is MCVE? – SexyBeast Jan 23 '18 at 20:49
There are names like `Scarlett O'Hara` or `Henry Hepburne-Scott`. Names are complicated. – Igor Tandetnik Jan 24 '18 at 01:20
Yeah of course of course. I am not trying to match all kinds of names, just a few.. :) – SexyBeast Jan 24 '18 at 06:20
