Individual fonts to a file name

[PapaiMark]

I received a file with a weird decorated and bold font.
Searching the net, nothing.
I discovered that using charmap it is possible (win10) to name a file even with the most unexpected fonts and symbols.
Colorize fonts, background, age, etc. Why not change the fonts itself, like
using a different font to name specific words like "setup" or changing the font for .lnk files, etc.
Just an idea.

Interesting. Could you attach such a file (zipped) to a post here?

Well... Stuff like colouring parts of filenames (differing from changing the entire filename, we already can do that; based on RegEx, mostly) would be intriguing to me, too.

Not sure about different fonts, though.

Sorry, the file is gone.
I myself could insert symbols, but couldn't change the font itself.
Maybe, who did it, modified a normal Windows font by changing the symbols to a draw of letters. It would be a wearisome job.
I remember that something like this was possible with the ancient Windows 98, typing right Alt + number pad numbers.

I really don't know how, but he (?) did it.

Using the font "Segoe MDL2 Assets" Unicode, all letters change to weird symbols.
He (?) modified this one? I don't know.

These are just Unicode characters of one font. No font change involved. Nothing new.

AHA! I found it in the internet.
I don't know how they do it.

There are some problems. Not all the text editors shows this font. Some shows ?????????????.txt
Seems that the forum considered the zip file with this font an "http error"

Who would've thought it was even possible to use fonts other than the system-defined one? I downloaded the file to see what happens. In Windows Notepad and Wordpad, the title bar shows the font. In Notepad++, the title bar shows ???????????.txt but the file tab shows the font.

The XY character table tells you something about it:

Code: Select all

So, these characters are extensions of the 16-bit Unicode set. It's not a different font, but fixed characters in the extended set.

OK: other view, but fiits here in the moment

XY seems to work well with such characters on fiilenames, text, etc.
But it badly fails with scripting...

Here XY interprets characters as 2-bytes. In real they are UTF-16, i.e *most* used chars can be expressed by 2 bytes, but much seldom used chars are 2*(2Bytes)! And '𝕿' is one of those...
The "directest" interfaces here are asc() and chr() - both don't understand this. (asc() i.e uses the number modulo x'10000'), chr() seems to only interpret the first 2 bytes.
(OK: there are more problems like substring: '𝕿' is 1 char, but 2*2bytes - at least it must be defined what happens...)

By the way: the name asc is very out of time: ascii is *only* 7-Bit! 8bit is something like ansi - language-dependent. Unicode is the full representation of 3 bytes (U+0000 - U+10FFFF), WIN-internal is UTF-16.

OK Don - what's to expect with these problems?

EDIT: correct definition of unicode

[admin]

chr() will work in next beta. The rest after TB.

[PeterH]

OK: saw your enhancement of chr(): very helpful
Especially that you can directly set the U+nnnn as chr(0xnnnn)! I.e. in this means we don't see the rules of UTF-16!

Now *every* try of asc() on such a "char" must fail - it will interpret the high surrogate as a full character.
As chr() defines that it will work on (only) one char, you could enhance it: test 2 bytes for a high surrogate, and if it is interpret 2*2 bytes (i.e. high and low surrogate) as a char.
1) yes: easy said
2) *can* be wrong - but not doing it *must* be wrong

I agree: strlen(), substr(), etc should wait...
... as you often said: needs more thinking!

[admin]

I had to do it, because there were old bugs in asc(). Next beta.

[PeterH]

Had a look at the curr beta
More than I thought I could ask for

(Maybe I should have asked some years ago, when I played with some exotic codepoints...
I love to use these as separators for lists of tokens: no risk a token contains them )
