The other interpretation is that all glyphs have widths which are an integral number of "columns". Western (latin, cyrillic, Greek) characters are a single column wide, while CJK characters are typically two columns wide. The (Unix98) wcwidth() function can be used to obtain the width (in columns) of a given wide character (wchar_t) in the current locale.

Can you clarify whether this is because the mapping of wchar_ts onto Unicode code points depends on the locale or whether the width of a Unicode code point depends on the locale. [I'm trying to understand whether we can be sure that the number of columns is portable so that different machines will apply the layout rule consistently (assuming the translation into UTF8 is consistent).] -- Alastair Reid alastair@reid-consulting-uk.ltd.uk Reid Consulting (UK) Limited http://www.reid-consulting-uk.ltd.uk/alastair/
