TextMesh Pro Zero-width space character is not zero width for monospace fonts

I am using TextMesh Pro 3.0.0 UGUI component. "0x200B" character is not rendered in regular fonts as expected but it is rendered when the font is monospace. I don't know if this is a bug or the expected behavior. But to me it makes more sense if this character is zero-width even in monospace (that is the case in HTML).

I locally fixed it by adding

 || charCode == 0x200B

to TMPRO_UGUI_Private.cs line 2083.

For the context, I am using this character for allowing words to line-break at certain points.

Edit: The solution above makes the caret disappear when input field is empty.

 

Do you mean when using <mspace> tag or with a particular font?

If a particular font, please provide a link to this font file.

 

@Stephan_B I am using the Roboto Mono font (Regular 400). Same thing also happens with <mspace> tag.

See the example image. The first text is regular font and the second one is monospace font.

 

Is your expectation that when using the Zero Width Space that it would remain zero width in all cases?

 

@Stephan_B Yes, that is what I expected. All UI frameworks I checked render it as zero width, does not matter if the font is monospace or not.

Sorry for the late reply.

 

@Stephan_B any progress on this? Do you agree that it is a bug?

 

That is an issue which I should be able to address in the next release.
