@MarkoLustro well my hello has been transformed to hel6o and then shown in Dotatnie font

yes, because in this alphabet is texrg and -3-2-1 +1+2+3 font

@MarkoLustro I have no idea what that means

simple : word 'to' -> t+o

t is main group write t

o is in r main group and write r-1

@MarkoLustro I honestly can not even guess what you mean by groups and + and - here, sorry, I'm a mathematician not a linguist:-)

r+(-1)

o=font r+ font -1 similar hangul (korean)

i'm mathematic too ;-)

@MarkoLustro I'm an english mathematician saying something is like hangul doesn't exactly simplify my understanding:-)

ok, in polish lang is s+'=ś

@MarkoLustro yeh that I understand:-)

this is this same o=r+font of name '-1'

ś is font s+ font '

in texrg is more complicated is only 5 chars and 6 modificators

@MarkoLustro OK but are those combinations in the opentype font or is that site using an external program to do the combining?

if chars is with this same 'line' group of chars You write main glyph and one char | symbol

Yes

this is a truble

trouble, meybe tex is good idea to convert normal tex into texrg

@MarkoLustro yes in the font, or yes separate program

I can write program in lua

can You help me write the style?

@MarkoLustro I have no idea what you are trying to do! so no. But you didn't answer if that web site is using a separate program to change hello to hel6o i assume it is. Is it in the server or in javascript in the page?

if this font is interesting to You please write to me

@MarkoLustro see above I'm not using email for this

yes

I see

meybe lua can convert it? \begin{texrg}some text \end{texrg}

\luado convert text into hel6o etc?

@MarkoLustro although I don't understand the problem, if you have a program that changes hello to hel6o then can you not just run that then typeset hel6o ?

[this is not good example because this font have ligatures ;-) ]

@MarkoLustro but on the website that was not done with font ligatures, the underlying text was changed

because i cant make ligatures

my ligatures mus be a whole dictionary

its impossible to create ligatures of any word

s

@MarkoLustro Just to back @DavidCarlisle up, I've no idea of what you are up to either :-)

@barbarabeeton it's just the same as tex, what could go wrong!

@MarkoLustro if you have a lua program that translates one string to another you can call that within luatex, here is an example that takes a string of cyrillic text in the document and uses a lua replacement program to convert that to a transliteration in latin script. As far as I understand your problem is the same, but with a more complicated transform

is posible to convert only in some place?

i need normal font

@DavidCarlisle Ah fishing for votes.... how typical

\begin{replace} test hello\end{replace}

no whole text

@MarkoLustro that's just a minor detail, you can turn the callback processing on and off at any point

Yes, this is good idea but how limit this callback only to some text

any example?

I need save callback before and restore it?

@MarkoLustro You install it at the start of the environment and remove it at the end

how ?

@MarkoLustro look at chickenze package that does all kinds of transformation and has commands to turn on or off,

simple example to convert 1 to 2

@DavidCarlisle Oddly, I've just had a direct mail about making a font ...

can You show me example?

@MarkoLustro there is a site for asking questions. Just ask a question on site with a real test example and show how far you got

@percusse just call me @egreg

@DavidCarlisle I think he is a bit subtler with the missing percent signs :P

@DavidCarlisle tex.stackexchange.com/questions/290547/…

how convert one char to other using lua ;-)

@MarkoLustro oh I remember that question, it's just not clear enough to answer.

Meybe now You can help me?

feel free to change my question to

better clearify

@MarkoLustro start from my example converting cyrillic to latin or start from chickenize which changes words and letters

@MarkoLustro I can't clarify or answer to do anything different from the answer I gave for cyrillic to latin.

Your words

@MarkoLustro This is chat room of that site :)

ok, thanks

if You would like to answer feel free to change my question

my english is ugly

no it not exist ;(

bye

@MarkoLustro Your english is a lot better than my Polish:-)
