Problems with a typecase_ pdf for f ligatures

[William]

Some readers have read the thread "A facility for entering Esperanto accented characters" and also have read the thread "Using the Hot Beverage character".

Here is a link to another typecase_ pdf. This one would be named typecase_f_ligatures.pdf except that I am having problems with using it.

If I try to copy and paste the glyphs into WordPad, then, instead of the desired ligature glyphs, WordPad displays glyphs of the underlying characters that make up the ligature character.

Is it possible to do anything so as to be able to copy the glyphs into WordPad please? I have tried Paste Special... with no success.

Problems continue.

I tried making typecase_spaces.pdf and could not copy out into WordPad, Word 97 and SC Unipad without the spaces each converting to U+0020 and I tried making typecase_combination_border_private_use_area.pdf and found that I could not copy out into WordPad (I got an array of spots which would not format to another font) but that I can copy out into Word 97 and into SC Unipad. From Word97 and SC Unipad, I can then copy and paste into WordPad.

Does anyone have any ideas about this please?

Here are links to the typecase_ pdfs.

The combination border, thirteen sorts including the special square space which is used in the typecase_ pdf, is implemented in my Quest text font and in my 10000 font: the combination border in the 10000 font using different glyphs from those in the Quest text font.

Yet this typecase_ pdf using some Private Use Area codes works well with WordPad.

Once copied from the pdf and pasted into WordPad, the characters need to be formatted using my Quest text font.

The glyphs are an extended version of those used in the item about percussion music about two-thirds of the way down the following web page.

So I suspect it's due to your PDF creator (PDFlib+ PDI 6.0.0p2 in case of Serif PagePlus 12). It is also possible that Acrobat Reader replaces the spaces into regular spaces, but it would surprise me.

Hope this is in the same vein...

When I try to search for a (designer name) in a font I do not always find them even when the name is clearly shown in any font display.

A hex view of the font shows the letters with hex 00 between each - so the search couldn't work. This is illustrated in your Code clip above.

This happens on fonts where the Microsoft name and Macintosh names are not the same. (With FC Autonaming, it is corrected).

Whazup? Is there a way to search either name? Any other thoughts?

[Erwin Denissen]

It's not possible right now.

FYI Microsoft naming fields are stored in UTF-16 format (2 bytes per plane 0 character), while Macintosh naming fields are stored in Mac format (one byte per character).

This happens on fonts where the Microsoft name and Macintosh names are not the same. (With FC Autonaming, it is corrected).

I think that the Macintosh name is in plain text yet the Microsoft name is encrypted in some way. It is interesting to look at a .ttf front using the WordPad program.

Do you find that it is the Microsoft name that is not picked up in the search?

As for the dump, I do not know how Erwin produced that dump, but I think that some dump programs put the ASCII-8 equivalent of each byte in the display at the right, regardless of the format of the file from which the data has been retrieved.

It looks like the left column is byte count at that point in hexadecimal (that is, in decimal, none so far, sixteen so far, thirty-two so far, and so on. The two large columns in the middle appear to be pairs of hexadecimal characters so that each pair is a byte within the range from hexadecimal 00 to hexadecimal FF. Each pair of bytes is one 16-bit character: it is a bit difficult to make out because of a historical quirk whereby the first byte of the pair is the second byte of the character. So the top line begins 3E00 which means a U+003E character, then 2000 which means a U+0020 character, then 3C00 which means a U+003C character, then D000 which means a U+000D character, and so on.

I think it unlikely (in fact I think it does not, but I am not in a position to say so congruently) that the spaces between the letters in the fourth column in any way affect the search. My guess is that they are just output put there so that a programmer looking at a dump can quickly pick-up where text strings are located in the code.

I hope that this helps.

While I was preparing my post, unknown to me, Erwin posted some information.

FYI Microsoft naming fields are stored in UTF-16 format (2 bytes per plane 0 character), while Macintosh naming fields are stored in Mac format (one byte per character).

Upon reading that I thought that I should therefore (or maybe just possibly) be able to find the name in amongst the black boxes using WordPad. I had in fact got a copy of my Sonnet to a Renaissance Lady font open in WordPad at the time. So I searched for the letter S using the WordPad search facility, with a view that I should hopefully be able to find the the word S o n n e t spaced out like that but with a black box between characters rather than spaces as shown here.

So I searched for S using the Edit Find... facility of WordPad and clicked the Find Next button a number of times, looking to see if that was the start of the spaced out word Sonnet at each click.

The Sixteenth click brought me to the clear unspaced-out plain text, namely the Microsoft platform information. The description information in that font is quite long, and it took until click seventy-four to get beyond it.

That appears to be at the start of the word Standard.

Click seventy-five brought me to the start of the word Sonnet.

I realized afterwards that I could have checked the Match case checkbox and got there in eleven clicks: however, it was fun searching.

Problems continue.

... I tried making typecase_combination_border_private_use_area.pdf and found that I could not copy out into WordPad (I got an array of spots which would not format to another font) but that I can copy out into Word 97 and into SC Unipad. From Word97 and SC Unipad, I can then copy and paste into WordPad.

http://www.users.globalnet.co.uk/~ngo/t ... e_area.pdf

I had a hunch that the lack of non-basic-latin glyphs in the pdf might be the cause of the problem with WordPad.

So I made the following, just adding a line of text at the top.

http://www.users.globalnet.co.uk/~ngo/t ... _area2.pdf

That did not work, so I tried removing all but one of the twenty-one uses of the "square space (private use area)" replacing those in the two lines of border glyphs each with two ordinary spaces and replacing the eight in the middle line between the border glyphs with one of them between > and < characters.

The pdf is as follows: I notice that the pairs of spaces appear each to have been replaced with a single space.

http://www.users.globalnet.co.uk/~ngo/t ... _area3.pdf

This works well with copy and paste to WordPad.

Once pasted, one needs to format with Quest text or with the 10000 font.

The format is typical Hex Editor with the hex characters on the left and translated letters on the right. Google for Hex Editors Freeware for a whole list. Good utility to have to investigate deeper.
