Fonts.WriteToUnicode

[alex59]

What exactly does the property Fonts.WriteToUnicode?

If I generate a pdf file without the property Fonts.WriteToUnicode = TRUE, the result seems to be the same as with this property. Even very strange characters like ᶄ ᶾ ẙ works without this property as well as with the property.

Hello alex59,

You would probably not be able to copy and paste characters from both of your test files in the same way!

The "ToUnicode" table is not mandatory for a font to display correctly inside the PDF file, however when you want to copy that text and be able to paste it in a third party product (e.g. Notepad/WordPad) - the "ToUnicode table is needed for the 'translation' process. Otherwise you might end up with "squares" pasted in notepad instead of the expected symbols.

So I presume that the .WriteToUnicode forces the creation of the "ToUnicode" table needed for text copying and pasting.

Kind regards,
Stefan

Hello Stefan

I allready supposed, that there could be a copy&paste problem without the proerty Fonts.WriteToUnicode. But there is not such problem.

I´ll set the property, because it probably can´t hurt.

Hello alex59,

I did some more reading - and it seems like with .WriteToUnicode set - the fonts are encoded using unicode character map set and not e.g. a narrower ones like say Windows-1251-1252 etc.

Kind regards,
Stefan
