I plan to commit this soon. The documentation for this function is giving the PDF docs build indigestion: [WARN] FOUserAgent - Glyph "?" (0x3a3, Sigma) not available in font "Couri= er". [WARN] FOUserAgent - Glyph "?" (0x3c3, sigma) not available in font "Couri= er". [WARN] FOUserAgent - Glyph "?" (0x3c2, sigma1) not available in font "Cour= ier". Found characters that cannot be output in the PDF document; see README.no= n-ASCII Not sure about a good workaround for this. Are there any characters within LATIN-1 that have interesting case-folding behavior? regards, tom lane
