Font tag is not working

[Nayan]

Steps to reproduce

1. In CKEditor after version 4.0 IE11 browser is supporting but problem is while editing time <font> tag is not supporting.
2. Below version 3.6 is not supporting to IE11 but <Font> tag is supporting
3. Please give me a solution. it would be appreciate to you.

Expected result

<Font> should support Or convert to <Span>

Actual result

<Font> is not supporting

Other details (browser, OS, CKEditor version, installed plugins) == IE9,IE10,IE11

AFAICS, the behaviour in CKE 4 and 3 is identical – CKEditor allows to load font tags (if configured correctly), but will transform them into spans when editor. Could you describe more precisely what doesn't work?

From what I have checked font tag is preserved in the editor but ACF by default does not allow it.

This can be configured with the following setting config.extraAllowedContent = 'font[*](*){*}';

@Nayan please see below to learn something more about ACF.

NOTE: @Reinmar version 4.0 preserves font tag so @Nayan was probably writing in general about version 4.
