New subject: Is there any way to automatically control the spacing between Chinese and non-Chinese characters?

2 Oct 2024


      I'm curious what Chinese font(s) you are using with ConTeXt?  Are they OpenType font,
or TrueType?

This is a preliminary solution for inserting spaces between Chinese

```ConTeXt
\mainlanguage[cn]
\language[cn]
\setscript[hanzi]
\usetypescriptfile[mscore]
\usebodyfont [mschinese,12pt]
\showglyphs
\startluacode

local glyph_id = nodes.nodecodes.glyph --node.id("glyph")
local node_insertbefore = node.insertbefore
local node_insertafter = node.insertafter
local node_new = node.new
local tex_sp = tex.sp
local function ischinesechar(c)
-- for more ranges:

return (c >= 0x04E00 and c <= 0x09FFF)
or (c >= 0x03400 and c <= 0x04DBF)
or (c >= 0x20000 and c <= 0x2A6DF)
end
function Thirddata.processmystuff(head)
local n = head
while n do
if n.id == glyph_id and ischinesechar(n.char) then
local n_prev = n.prev
if n_prev
and n_prev.id == glyph_id
and not ischinesechar(n_prev.char)
then
local glue = node_new("glue")
glue.width = tex_sp("0.25em")
glue.stretch = tex_sp("0.25em")
print("insert space before:", utf8.char(n.char))
head, glue = node_insertbefore(head, n, glue)
end
local n_next = n.next
if n_next
and n_next.id == glyph_id
and not ischinesechar(n_next.char)
then
local glue = node_new("glue")
glue.width = tex_sp("0.25em")
glue.stretch = tex_sp("0.25em")
print("insert space after:", utf8.char(n.char))
head, glue = node_insertafter(head, n, glue)
n = glue.next
end
end
n = n.next
end
return head, done

hi,
Is there any way to automatically control the spacing between Chinese and non-Chinese characters?
I noticed that there is a tracker that tracks character types and annotates them.
But I don't know much about lua and the underlying tex.
Any suggestions would be greatly appreciated.
For example, glue is automatically added between Chinese characters and English or numbers.
