That's what I originally thought - but every implementation I've
investigated comes up with the letter 'x'. I have seen 'x' with serifs
in lists of Lao vowels, but I'm not sure that the Lao vowels were
actually typed. I must say 'x' works very well as a bearer for SE
Asian combining marks.

I originally raised the issue because I am not sure what having a
letter reclassified as common would do to the definition of CLDR
tailorings. The Garshuni writing system could have an interesting one
- Syriac consonants with Arabic marks - but I suspect Arabic vowels
being primary ignorables prevents any ridiculous results.
