Hi sir
I am interested to use the Malayalam language with my 128X32 pixel SSD1306 display. How to make a font for printing Malayalam text on my OLED?

You need (a) a suitable font file, perferable in .bdf format and (b) you need to figure out the unicode range for this language. Assuming, that the range is from 0xd00 to 0xd7f, it might look like this (derived from GNU unifont):
The code for this font is this:

I have a problem, Malayalam font cant read in Arduino IDE software and not showing in OLED. How to solve it?
Code

but the Glyph is working
code(My name in Malayalam (เด

output
working drawUTF8

And also Malayalam has Dependent vowel signs. It's 'x' position is not normal. And has Two-part dependent vowel signs, when we use Two-part dependent vowel signs the character position in between Two-part dependent vowel signs.

In order to use u8g2.print() you need to enable it (as mentioned above). However this is only the first step. As a second precondition, you need to ensure, that your editor is able to operate in UTF8 mode: The resulting C file must be saved as UTF8 text file. The Arduino IDE by default works in UTF8 code, you should be able to directly type in or copy Malayalam glyphs from a char set tool. Especially there should not be these boxes. Instead you should see the glyphs in the C code string itself. I mean, the gylphs should be visible like here: https://github.com/olikraus/u8g2/blob/master/sys/arduino/u8g2_page_buffer/Chinese/Chinese.ino#L280
And also Malayalam has Dependent vowel signs. It's 'x' position is not normal. And has Two-part dependent vowel signs, when we use Two-part dependent vowel signs the character position in between Two-part dependent vowel signs.
U8g2 is made for embedded systems with very limited resources. So... it is by far not as powerful as a windows true type font rendering system (which requires magabytes of code).
Moreover, as a open source project we unfortunately do not have the resources to implement the required kerning algorithms for your language. At the end I assume it is up to you to output each glyph individually and shift the next glyph depending of the previous glyph into the right position.
There had been some attempts to implement support procedures for this, but I am not sure whether this will help you. There is an undocumented function called drawExtUTF8, see #529

Malayalam Unicode table
The characters may be denoted by Unicode symbols in the range 0D00-0D7F. Below a table, that will show them if your browser supports UTF-8 and you have a Malayalam font installed.
Consonants
The values 0D15-0D39 denote consonants (or, rather, syllables consonant+a), except for 0D29 which doesn't exist.
A selection of conjunct consonants
When combined with vowel diacritics some consonants change shape.
More details
Vowels that modify consonant symbols
The values 0D3E-0D43, 0D46-0D48, 0D4A-0D4D, 0D02-0D03 denote various modifying vowels, used to change the an into a different vowel (or no vowel). Here shown following the symbol เด ka.
How to do these with the u8g2 library?
I found a similar problem in the Arabic language
How you solved this in the Arabic Language?
How can I solve it in the Malayalam language?
More
This Font contains more characters in the Malayalam.
I want to convert that font. But the problem is that the Fony software doesn't show Malayalam characters.
This font has some additional characters in Malayalam start from 0xD6C to 0xED59. I want to include those characters also.

Hello @olikraus
I think you have solved all the problems in the u8g2 library related to Arabic.
Some of them are below
The Malayalam language has similar conditions are below
And also two characters combine and form a new character
How can I create a fully working Malayalam font? Can I use any script for that?

I think you have solved all the problems in the u8g2 library related to Arabic.
not true. This is still open i think.
Arabic and Malayalam require the following extra steps:
- Combination of glyphs
- Construction of new glyphs based on two other glyphs
The first point is partly supported by the above mentioned ExtUTF8 function.
The second point should be handled by your text editor. Or, if this is not the case, you need to do a string replace step before printing: Search for two chars replace it by one other char. However, I do not know whether the second point is true for you.
I want to convert that font. But the problem is that the Fony software doesn't show Malayalam characters.
Fony is only for bdf editing, but I think the fonts you provided are ttf only, so otf2bdf and bdfconv are sufficient.

1. Combination of glyphs
The first point is partly supported by the above mentioned ExtUTF8 function.
In my table, I want to fix the second character for all other characters
example:
0x0d28, 0x0d4d, 15, /* เดจ and เต */
in here the first char 0x0d28 is changing to any char but the second char 0x0d4d and gap reduction value are fixed. Is this possible?
And I am confused with the last value
/* this line terminates the table */
0xffff, 0xffff, 0xffff
What are you mean by that line?
2. Construction of new glyphs based on two other glyphs
The second point should be handled by your text editor. Or, if this is not the case, you need to do a string replace step before printing: Search for two chars replace it by one other char. However, I do not know whether the second point is true for you.
I fund a font that contains more characters for the construction of new glyphs based on two other glyphs.
It starts from 0xECE3 to 0xED59 and also I found the range starts from 0xE000to 0xF8FFcan use for private use.
Can replace two glyphs by one as shown in the picture above? Is there any code available for that?
3. Main Need
Fony is only for bdf editing, but I think the fonts you provided are ttf only, so otf2bdf and bdfconv are sufficient.
I am using Windows 7. Can you suggest me a software to convert TTF to bdf?

You probably need some kind of search and replace functionality.
There is a lot of information in the net. But I do not know, whether this fits to Arduino World...

You need (a) a suitable font file, perferable in .bdf format and (b) you need to figure out the unicode range for this language. Assuming, that the range is from 0xd00 to 0xd7f, it might look like this (derived from GNU unifont):
The code for this font is this:
