Because of the confusing behavior of Python Regex, \w, \b etc. includes locale language characters.

For instance

Snippets/markdown/text_shortmath.snippets

Lines 21 to 24 in 8593cbd

	context "text()"
	snippet "\b(\D?)ce" "行间化学 Inline Chemical" r
	`!p snip.rv = match.group(1) + ('' if match.group(1) in before_puncs else ' ')`$\ce{${1:${VISUAL}}}$ $0
	endsnippet

我ce<Trigger>

would not expand the snippet.

According to Python re doc, the solution is to add (?a).

For the above example is

(?a)(\D?)\bce

 context "text()"
-snippet "\b(\D?)ce" "行间化学 Inline Chemical" r
+snippet "(?a)(\D?)\bce" "行间化学 Inline Chemical" r
 `!p snip.rv = match.group(1) + ('' if match.group(1) in before_puncs else ' ')`$\ce{${1:${VISUAL}}}$ $0
 endsnippet

Please remember to move \b to (\D?) or (\W?) behind.
