National letters - input text on screen
« on: August 03, 2023, 05:00:53 pm »
Hi everyone!

I have one issue, where I need your help with. I made field, where you can write name of your character, when you making it. Everything looks fine, but I can't figure out how can I input my national (polish) letters in (ę, ó, ą, ś, ł, ż, ź, ć, ń).

Here is my code:

(click to show/hide)

I tried everything, for ex. I tried to implement unicode numbers to this "else if", but only two letters works ("Ó, ó"). Another letters are replaced by another.

Can you help me with that issue?

Assuming name_input_string is a std::string (hard to tell without a namespace) try:

Code: [Select]
char_creation_name_input_txt.setString(sf::String::fromUtf8(name_input_string.begin(), name_input_string.end());

Unfortunetly, that doesn't work. Characters still doesn't show up or are replaced by other characters, when I delete that "else if".

I tried to change advanced save settings in Visual Studio 2022 from Middleeuropean (codepage 1250) to UTF-8, but that doesn't works too.

Yes, name_input_string is exacly string.

I have to ask but are the characters you are hoping to see within the range you allow?

unicode 65-90 and 97-122.

Yes, after fallahn suggestions I deleted that "else if" with unicode range. Unfortunetly when I do this, my national letters are replaced by other letters, for ex. "ń" is replaced by "D".

EDIT:
Additional info! When I just draw texts on screen, I just write letter "L" before string. For ex.:

(click to show/hide)

This letter "L" works, but when I want to write text directly on screen, that doesn't works.

Ah, have you tried using a wide string? i.e. std::w_string

There are 'better' string types for unicode characters but, apparently, SFML doesn't support them yet.

If name_input_string is an std::string and you do:
Code: [Select]
name_input_string += ev->text.unicode;then the 4-bytes unicode character will be narrowed down to only one byte and lose information.
For example "ń" (unicode character U+0144) becomes "D" (unicode character U+0044). Only the least significant byte is added to the string.

You can use sf::String instead of std::string to store unicode characters.
Alternatively you could encode unicode characters to UTF-8 encoding to store them in an std::string.

And that finally works!

I just change string to String, as you said.

Thank you kimci86 and everyone else for help!
