Korean characters missing

[Avital-Kapiloff]

Hi,
I'm creating a PDF and I need support for Korean, Amharic, Polish, English. I can't find one font that contains them all.
I don't know the content of the text so I can't specify what font to use.
How do I overcome that issue?
Thanks.

example of content that should work...

var dd = {
	content: [
        'ASCII-1:  A B C D E F G H I J K L M N O P Q R S T U V W X Y Z',
        'ASCII-2:  a b c d e f g h i j k l m n o p q r s t u v w x y z',
        'ASCII-3:  0 1 2 3 4 5 6 7 8 9',
        'ASCII-4:  . , : ; - _ ! ? / " \' ` ^ ~ * + = \\ | # $ @ % & ( ) < > [ ] { }',
        'German:  Ä Ö Ü ä ö ü ß',
        'Czech-1:  Á Č Ď É Ě Í Ň Ó Ř Š Ť Ú Ů Ý Ž',
        'Czech-2:  á č ď é ě í ň ó ř š ť ú ů ý ž',
        'Romanian-1:  Ă Â Î Ş Ţ',
        'Romanian-2:  ă â î ş ţ',
        'Slovenian-1:  Č Š Ž',
        'Slovenian-1:  č š ž',
        'Slowak-1:  Á Ä Č Ď É Í Ľ Ĺ Ň Ó Ô Ŕ Š Ť Ú Ý Ž',
        'Slowak-2:  á ä č ď é í ľ ĺ ň ó ô ŕ š ť ú ý ž',
        'Special:  § ´ ² ³ ° µ €',
        'polish: Cześć',
        'Amharic: ሰላም',
        'Korean: 여보세요'

Same problem, but other languages. CJK, arabian,....
At the moment mixing ttf fonts with FontForge, not sure if all characters are working.

Thank you.

If you did not find one font file with all the necessary character sets. Of if not you must use different fonts for different character sets, example:

var dd = {
	content: [
		{text: 'Text A', font: 'Roboto'},
		{text: 'Text B', font: 'Otherfont1'},
		{text: 'Text C', font: 'Otherfont2'},
	]
};

[malloc32]

But the problem is that I don't know when I have to use Roboto or when I have to use Othefont because I don't know the language of the text.

Then is required font file with all necessary character sets.

@liborm85 Thank you for your response!

I decided to check the content of the text and only then decide what font to use depending on the language it's working fine except the Korean. is there different behaver for Korean letters?

using this font https://fonts.google.com/specimen/Nanum+Gothic?selection.family=Nanum+Gothic&selection.subset=korean - i tried a few diffaret fonts it still didn't work for me (https://www.google.com/get/noto/#sans-kore)

vfs_fonts.js.zip

any clue what is going on? I'm getting an empty space where the Korean text should go

Thanks!

Probably font NanumGothic not support this characters and therefore blank space is displayed.

I tried a bunch of other korean fonts it didn't work for me

[Avital-Kapiloff]

I was wondering if it could be the way the font is built that the library cant read it?
I think I'm having the same issue as this #1168

[malloc32]

Same problem with korean (this is the output, japanese, arabian, chinese, greek an. korean)
have a problem with one chinese character.

[Avital-Kapiloff]

I used the exact font that he mentions in this comment to solve the issue other fonts didn't work for me.
