Hello People I am just getting my hands on to Infopath so need your expertise on the below issue. I have a validation on a text field in (Infopath 2007) for UTF-8 encoding. I am doing it from the frontEnd using this expression [^\u0000-\u007F]. To get the funny charcter press alt + number 1 +number 2 Infopath did validate the first character but not the whole string. I have few combination using ".", ^$ but woithout any luck. Can some one please point me towards the right direction? Thanks in advance. Jaber

Hello All I have worked out the pattern and the pattern is picking up any character which is not part of the UTF-8 encoding. Here is the pattern :- "[^\u0000-\u007F]|[^\u0000-\u007F]*|.*[^\u0000-\u007F].*"
