Hi. When in a "properties" file containing the localized message patterns, there is a single quote in a pattern, it doesn't appear in the output and prevents the conversion of the curly-braced variables that follow it. E.g. if a "math_messages_fr.properties" contains this line: ---CUT--- OUT_OF_RANGE=La valeur {0} est hors de l intervalle [{1}, {2}] (message localisé) ---CUT--- the ouput I get is ---CUT--- La valeur -1 est hors de l intervalle [0, 3] (message localisé) ---CUT--- as expected. However, when the pattern is changed to: ---CUT--- OUT_OF_RANGE=La valeur {0} est hors de l'intervalle [{1}, {2}] (message localisé) ---CUT--- (with a single quote before the word "intervalle"), the ouput I get is now ---CUT--- La valeur -1 est hors de lintervalle [{1}, {2}] (message localisé) ---CUT--- In the Javadoc of the "Properties" class, they say: "Escapes are not necessary for single and double quotes; however, by the rule above, single and double quote characters preceded by a backslash still yield single and double quote characters, respectively." [I also tried escaping with a single slash character but the result is the same.] So it seems that it is not the case when using CAL10N. Did I miss something from the documentation?
