如何解决RichView导出Html看不到中文问题

1、 问题描述：

调用RichViewEdit.SaveHTMLToStream的方法可以生成html文件，但是默认导出的不是中文码，而是ASCII码。如何解决这个问题呢？

2、解决办法：

这个方法的最后一个参数可以用来解决这个问题

SaveHTMLToStream(Stream: TStream; const Path, Title, ImagesPrefix: String; Options: TRVSaveOptions):Boolean;

将Options参数设置为[rvsoUTF8]即可，参数说明如下：

{ Options for saving HTML files, TCustomRichView.SaveHTML and SaveHTMLEx methods }
TRVSaveOption = (
rvsoOverrideImages, // Overwrite image files (if not set - use unique)
rvsoFirstOnly, // Save only heading part of HTML
rvsoMiddleOnly, // Save only middle part of HTML (document itself)
rvsoLastOnly, // Save only ending part of HTML
rvsoDefault0Style, // Do not save properties for the 0-th text style
rvsoNoHypertextImageBorders, // Supress borders for hypertext images
rvsoImageSizes, // Write image size
rvsoForceNonTextCSS,// Always use CSS for non-text items
rvsoUseCheckpointsNames, // Use "checkpoint names" instead of indices
rvsoMarkersAsText, // Save paragraph bullets/numbering without <UL>/<OL>
rvsoInlineCSS, // Write CSS directly in <P> and <SPAN> tags
// (only for SaveHTMLEx)
rvsoNoDefCSSStyle, // Use named CSS for all text styles, even for
// TextStyles[0] (by default, properties of
// TextStyles[0] are assigned to BODY and TABLE).
// This option generates larger HTML (not recommended).
// (only for SaveHTMLEx)
rvsoUseItemImageFileNames, // If set, images having specified
// (in extra string properties) file names will not
// be saved, but their file names will be written
// in HTML (relative to the HTML file path)
rvsoXHTML, // Save XHTML
rvsoUTF8); // Use UTF8 encoding
TRVSaveOptions = set of TRVSaveOption;
