I want to store a string with an accent like “aà” to an FString.

Doing this:

FString a = TEXT("aà");

I’m getting those errors:

error C2018: unknown character '0x22'
error C2018: unknown character '0x29'
error C3688: invalid literal suffix 'a")GGABLE'; literal operator or literal operator template 'operator ""

Anyone can explain me how to do it correctly? Thank you!

Sorry i’m not so good at this but…

FString a = TEXT("a\x00e0");

where \x00e0 utf-8 character code

you can use “u” too

Numeric character references:

  • \ + up to 3 octal digits
  • \x + any number of hex digits
  • \u + 4 hex digits (Unicode BMP, new in C++11)
  • \U + 8 hex digits (Unicode astral planes, new in C++11)

Thank you! that worked! But, can you explain me why is the \x ?

I found this website:

And it says to use \u instead of \x. Do you know if there are some differences?

According to c++ spec:
https://en.cppreference.com/w/cpp/language/escape

For unicode you will have to use /u not /x
