Since Bengali is not well supported by all browsers, the recommended approach would be to add the Bengali font in the list of font families specified on the body selector of the RTE.default.contentCSS stylesheet. For example:

body { font-family: Verdana, sans-serif, Likhan; }

For some reason, with some fonts, the lines may overlap when using larger font sizes. It is the case with the Bengali Likhan font in Firefox 1.0.2. This may also be corrected through the stylesheet. For example:

body { font-family: Verdana, sans-serif, Likhan; line-height: 1.4; }

Note that, when using the Bengali Likhan font, a line-height with em or % unit may not produce any effect in Firefox 1.0.2.
