This is a preliminary solution for inserting spaces between Chinese characters and non-Chinese characters ```ConTeXt \mainlanguage[cn] \language[cn] \setscript[hanzi] \usetypescriptfile[mscore] \usebodyfont [mschinese,12pt] \showglyphs \startluacode Thirddata = Thirddata or {} 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: -- https://wiki.contextgarden.net/List_of_Unicode_blocks 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 end nodes.tasks.appendaction("processors", "after", "Thirddata.processmystuff") \stopluacode \starttext 今天出去买菜花了5000元。 新MacBook Pro有15\%的CPU性能提升。 \stoptext ``` On Tue, Oct 1, 2024 at 2:07 PM wrote:

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.
