Calculate column numbers assuming that space and all ASCII > printing characters have equal width, and assuming tab stops every 8 > columns.". This doesn't say how other characters should be counted, > although for the results of wcswidth seem appropriate. Then GCC is not using wcswidth to count or it is setting the locale inappropriately because it is counting 2 for ñ and 3 for 中, while it should be 1 and 2.
