To get some clarification into this, I propose voting on whether basic misspellings and correction of cx and ch into ĉ should be allowed. Important point: When quoting from a source that uses the x- or h-system, one might want to keep this and not over-correct.
Addition: This is not a duplicate of "what should our standpoint be on edits?", it's to add a clarification to that. Plus, see the answer which proposes posting questions like these (in that question).
