Updating to PHP 7.3 issues some Warnings about tcpdf

[nicolaasuni]

would you please check again with the latest version?

Just updated to 6.3.3 but they are still there :(
It's the same behavior, the warnings come from calling $tcpdf->GetStringWidth().

The image deletion problem is also still present, same as before, when using a custom font-family.

Edit: I just noticed that the image deletion now happens always, and not just with custom font-family, so it's worse than before :/

I have just pushed the 6.3.4 version that should solve the image issue.
I can accept a PR for the warnings but I am not actively working this as I would like to concentrate on tc-lib-pdf instead.

Thanks! I removed the GetStringWidth calls for now. Maybe I'll look into it some time.

I had the same error Warning: array_map(): Expected parameter 2 to be an array, bool given in with upgrading to PHP v7.4.
TCPDF version 6.3.5.
I replaced $tcpdf->GetStringWidth(utf8_decode('textWithSpeçïálCharacters')) to $tcpdf->GetStringWidth('textWithSpeçïálCharacters') and now it works.
